DEFENDANT CITY OF FORT COLLINS’ MOTION TO STRIKE PLAINTIFF’S
EXPERT DAN CORSENTINO PURSUANT TO FED. R. EVID. 702
Defendant City of Fort Collins, by and through their undersigned counsel, Hall & Evans,
LLC, hereby submit the following as their Motion to Strike Plaintiff’s Expert, Dan Corsentino,
pursuant to Fed. R. Evid. 702:
CERTIFICATE OF CONFERRAL
Undersigned Counsel for the City of Fort Collins, conferred with Counsel for the Plaintiff,
regarding the relief requested in this Motion. Counsel for Plaintiff indicated an objection to any
such relief. Therefore, this Motion is opposed.
I. INTRODUCTION
This matter arises out of Plaintiff’s arrest on April 7, 2022, by Defendant and former Fort
Collins Police Officer, Jason Haferman, and the ensuing investigation and prosecution for the
crime of Driving Under the Influence (“DUI”). Plaintiff claims Defendant Haferman’s actions
somehow implicate the City of Fort Collins (“City”). In particular, the Complaint attempts to set
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg

forth claims against the City, pursuant to 42 U.S.C. § 1983, for an unconstitutional pattern and
practice, a failure to train and supervise, and a violation of “due process” under the Fourth
Amendment.
As part of his efforts to prove his claims against the City, Plaintiff endorsed Dan Corsentino
as an expert. (See generally opinions of Dan Corsentino, attached hereto as Exhibit A) (“Report”).
In rendering his opinions, however, Mr. Corsentino completely omits any analysis regarding the
actions of Defendant Haferman and the determination of probable cause, vis-à-vis the City, and
instead relies on broad, sweeping, unsupported, and conclusory criticisms. Furthermore, Mr.
Corsentino’s opinions do not provide any proper analysis regarding any alleged unconstitutional
pattern or practice, a failure to train, or a failure to supervise, and instead relies on a dilution of the
proper Constitutional standard, akin to nothing more than negligence or malpractice. In doing so,
Mr. Corsentino effectively and incorrectly dictates to a jury, what law should apply. Mr.
Corsentino’s opinions should, therefore, be excluded from presentation to a jury pursuant to Fed.
R. Evid. 702 and applicable case law. See e.g. Specht v. Jensen, 853 F.2d 805 (10th Cir. 1988);
Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993), and Kumho Tire Co. v. Carmichael,
526 U.S. 137 (1999).
II. FACTS 1
On June 11, 2021, former Fort Collins Police Officer Jason Haferman, pulled Plaintiff over
in his truck, for accelerating too quickly. (ECF 33 at ¶ 51). After questioning by Officer Haferman,
Plaintiff admitted he had one beer, several hours earlier in the day. (ECF 33 at ¶ 52). Officer
Haferman asked Plaintiff to participate in roadside tests, to prove he was safe to drive (ECF 33 at
1 The recited facts are taken as true only for the purposes of this Motion to Strike.
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg
2 of 13

¶ 53). After performing the roadside tests, Officer Haferman arrested Plaintiff and charged him
with driving under the influence (ECF 33 at ¶ 62). On November 10, 2021, Officer Haferman
received Plaintiff’s blood test results, which were negative for alcohol or drugs (ECF 33 at ¶ 79).
The charges against Plaintiff were subsequently dropped by the District Attorney (ECF 33 at ¶ 80).
Plaintiff claims Officer Haferman arrested him without probable cause in violation of the
Colorado Constitution and his Fourth Amendment rights. Plaintiff bases his claims on a belief the
City both maintained an unconstitutional policy with respect to DUI arrests, and failed to train
and/or supervise Officer Haferman.
III. ARGUMENT
A. Corsentino’s Opinions
In his Report, Mr. Corsentino offers the following opinions:
1. Sergeant Allen Heaton and Corporal Jason Bogosian failed in the following areas:
a. Failed to review Officer Haferman's written reports,
b. Failed to review BWC footage,
c. Failed to review results of blood tests,
d. Failed to randomly and systematically follow up with arrestees who
made complaints about Officer Haferman,
e. Failed to communicate with the District Attorney on the status of certain
cases based on the volume of DUI arrests Haferman was involved in,
f. Failed to notify Command Staff, specifically the Chief of Police, that there
was a pattern of behavior developing in their DUI enforcement section,
g. Failure to train properly on DUI Enforcement, and
h. Failed to do a ride along with Officer Haferman to assess how he
established probable cause for a traffic stop.
(Ex. A at 22)
2. The recurring pattern of wrongful arrests and ethical lapses attributed to Officer
Haferman raises serious concerns about the department's training protocols,
supervision mechanisms, and ethical standards enforcement.
(Ex. A at 22)
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg

3. (T)he supervisory roles of Sergeant Allen Heaton in particular comes under
scrutiny, due to his apparent lapses in addressing critical deficiencies in Haferman
not having accurate and detailed police reports, and it does not appear that Heaton
handled internal affairs investigations into performance complaints that had been
made about Haferman very effectively.
(Ex. A at 22-23).
The report also offers conclusory statements, respecting topics such as “Supervisor
Oversight,” (Ex. A at 11); “Early Red Flags,” (Ex. A at 11); “Performance Reviews and Feedback
of Jason Haferman,” (Ex. A at 18) and; “Maintaining Ethical Standards.” (Ex. A at 20).
Corsentino’s observations involve the City’s review of body-camera footage, activation of
Haferman’s body camera, criticisms of Haferman’s report writing, and sweeping statements
regarding ethics in policing.
B. Applicable Law
To establish liability of a public entity under 42 U.S.C. §1983, “a plaintiff must show (1)
the existence of a municipal custom or policy and (2) a direct and causal link between the custom
or policy and the violation alleged.” Jenkins v. Wood, 81 F.3d 988, 993 (10th Cir. 1996), citing
City of Canton v. Harris, 489 U.S. 378, 385 (1989). The Supreme Court described the
requirements a plaintiff must meet to impose public entity liability as follows: “It is not enough
for a §1983 plaintiff merely to identify conduct properly attributable to the municipality. The
plaintiff must also demonstrate that, through its deliberate conduct, the municipality was the
‘moving force’ behind the injury alleged. That is, a plaintiff must show that the municipal action
was taken with the requisite degree of culpability and must demonstrate a direct causal link
between the municipal action and the deprivation of federal rights.” Bd. of Cnty. Comm’rs of
Bryan Cnty. v. Brown, 520 U.S. 397, 404 (1998) (emphasis added).
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg
4 of 13

Under these standards, municipal liability may arise only out of official customs or policies,
or for the actions of a final policymaker to any extent that such policies, customs, or policymakers
can be shown to be responsible for a constitutional violation. See Brown, 520 U.S. at 403-404.
Establishing deliberate conduct and the “requisite degree of culpability,” means municipal liability
attaches only where “a deliberate choice to follow a course of action is made from among various
alternatives by the official or officials responsible for establishing final policy with respect to the
subject matter in question.” Pembaur v. City of Cincinnati, 475 U.S. 469, 483 (1986); Myers v.
Oklahoma Cnty. Bd. of Cnty. Comm’rs, 151 F.3d 1313, 1319 (10th Cir. 1998).
“Under § 1983, government officials are not vicariously liable for the misconduct of their
subordinates. ‘There is no concept of strict supervisor liability under § 1983.’” Serna v. Colo.
Dept. of Corrections, 455 F.3d 1146, 1151 (10th Cir. 2006), citing Jenkins v. Wood, 81 F.3d 988,
994 (10th Cir. 1996); see also Bass v. Robinson, 167 F.3d 1041, 1048 (6th Cir. 1999) (“Liability .
. . must be based upon more than a mere right to control employees.) “Where a plaintiff claims
that the municipality has not directly inflicted an injury, but nonetheless has caused an employee
to do so, rigorous standards of culpability and causation must be applied to ensure that the
municipality is not held liable solely for the actions of its employee.” Schneider v. City of Grand
Junction Police Dep’t, 717 F.3d 760, 770 (10th Cir. 2013), citing Brown, 520 U.S. at 405. “The
causation element is applied with especial rigor when the municipal policy or practice is itself not
unconstitutional, for example, when the municipal liability claim is based upon inadequate
training, supervision, and deficiencies in hiring.” Schneider, 717 F.3d at 770, citing Martin A.
Schwartz, Section 1983 Litigation Claims & Defenses, § 7.12.
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg

“[F]or claims of inadequate. . . training. . . a plaintiff ‘must demonstrate that the municipal
action was taken with deliberate indifference as to its known or obvious consequences.’”
Hernandez v. City and Cnty. of Denver, 2022 U.S. Dist. LEXIS 151302, at *3 (D. Colo. Aug. 23,
2022), citing Waller v. City and Cnty. of Denver, 932 F.3d 1277, 1284 (10th Cir. 2019). “[A] less
stringent standard of fault for a failure-to-train claim ‘would result in de facto respondeat superior
liability on municipalities.’” Hernandez, at *3, citing Connick v. Thompson, 563 U.S. 51, 62
(2011), citing City of Canton v. Harris, 489 U.S. 378, 392 (1989). “A pattern of similar
constitutional violations by untrained employees is ordinarily necessary to demonstrate deliberate
indifference for purposes of failure to train.” Erickson v. City of Lakewood, 489 F. Supp. 3d 1192,
1208 (D. Colo. Sept. 24, 2020), citing Connick, 563 U.S. at 62.
“We treat allegations of failure to supervise (which often may be indistinguishable from
failure to train) the same way. Whitewater v. Goss, 192 Fed. Appx. 794, 797 (10th Cir. 2006)
referring to Medina v. City & County of Denver, 960 F.2d 1493, 1500 (10th Cir. 1992); Schepp
v. Fremont County, 900 F.2d 1448, 1454 (10th Cir. 1990); Meade v. Grubbs, 841 F.2d 1512,
1527-28 (10th Cir. 1988).
C. Corsentino’s Proposed Expert Opinions Must Be Excluded by the Court as Any Such
Opinions Do Not Meet Rule 702’s Reliability or Relevancy Requirements.
Pursuant to Daubert and Kumho Tire, an expert is required to offer opinions based on
reliable methodology and which are relevant to the issues in the matter. The Court may determine
initial questions respecting admissibility of expert testimony pursuant to Fed. R. Evid. 104(a).
“The court must decide any preliminary question about whether a witness is qualified, a privilege
exists, or evidence is admissible.” Fed. R. Evid. 104(a). Rule 104(a) requires a proponent of the
testimony to salvage its admissibility by a preponderance of the evidence. See Ralston v. Smith &
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg
6 of 13

Nephew Richards, Inc., 275 F.3d 965, 970, n. 4 (10th Cir., 2001); In Re Breast Implant Litigation
11 F.Supp. 2d 1217, 1222 (D. Colo. 1998); See also In Re Williams Sec. Litig., 496 F.Supp. 2d
1195, 1230, and n. 10 (N.D. Okla. 2007).
Additionally, a determination as to the admissibility of Corsentino's proposed expert
opinions should also be made under Fed. R. Evid. 702 which provides in pertinent part:
A witness who is qualified as an expert by knowledge, skill, experience,
training, or education may testify in the form of an opinion or otherwise if:
(a) the expert’s scientific, technical, or other specialized knowledge will
help the trier of fact to understand the evidence or to determine a fact in
issue; (b) the testimony is based on the sufficient facts or data; (c) the
testimony is the product of reliable principals and methods; and (d) the
expert has reliability applied the principles and methods to the facts of the
case.
In Daubert, the Supreme Court interpreted Rule 702 to mean that when a trial judge is
“[f]aced with a proffer of expert scientific testimony ... the trial judge must determine at the outset
... whether the expert is proposing to testify to (1) scientific knowledge that (2) will assist the trier
of fact to understand or determine a fact in issue.” United States v. Benally, 541 F.3d 990, 994
(10th Cir. 2008), citing Daubert, 509 U.S. at 592. To be reliable under Daubert, proposed expert
testimony must be supported by scientific principles and by “appropriate validation – i.e., ‘good
grounds,’ based on what is known.” Dodge v. Cotter Corp., 328 F.3d 1212, 1222 (10th Cir. 2003).
Daubert directs a district court making a Rule 702 reliability assessment to consider whether the
testimony: (1) can be and has been tested; (2) was subjected to peer review and publication; (3)
has a known or potential rate for error; and (4) has attained general acceptance in the relevant
scientific community. Magdaleno v. Burlington N.R.R. Co., 5 F. Supp. 2d 899, 902 (D. Colo.
1998); see Truck Ins. Exch. v. MagneTek, Inc., 360 F.3d 1206, 1210 (10th Cir. 2004). In certain
cases, “the relevant reliability concerns may focus upon personal knowledge or experience.”
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg
7 of 13

Kumho Tire, 526 U.S. at 150. However, requiring expert opinions to be based on reliable
methodology is essential, because an expert is not permitted to speculate. Milne v. USA Cycling
Inc., 575 F.3d 1120, 1133-34 (10th Cir. 2009).
The Court’s gatekeeping “requires more than simply taking the expert’s word for it.”
United States v. Nacchio, 555 F.3d 1234, 1258 (10th Cir. 2009), citing Fed. R. Evid. 702 Advisory
Committee Note (2000). “[N]othing in either Daubert or the Federal Rules of Evidence requires a
district court to admit opinion evidence that is connected to existing data only by the ipse dixit of
the expert. A court may conclude that there is simply too great an analytical gap between the data
and the opinion proffered.” Gen. Elec. Co. v. Joiner, 522 U.S. 136, 146 (1997). Expert opinions
“are valueless as evidence without exploration of the underlying facts and rationale showing the
path from the facts to the opinion.” U.S. v. R.J. Reynolds Tobacco Co., 416 F. Supp. 316, 325
(D.N.J. 1976).
1. Corsentino’s Opinions are not Based on any Reliable Methodology.
Mr. Corsentino’s Report offers generalized criticisms of various generalized factual
aspects, but provides no supporting standards, grounded in reliable and repeatable methodology.
For example, the Report states Mr. Corsentino was retained to offer opinions with respect to
“minimal baselines of supervision in policing,” and opines “not even the most minimal or baseline
levels of supervision were exercised with respect to Officer Haferman,” but no such baselines are
identified. (Ex. A at 7 & 11); Mr. Corsentino believes the FCPS Command Staff were not adhering
to “minimal standards of supervision”, but no such standards are identified or defined. (Ex. A at
9); Mr. Corsentino states, “a minimal standard for this type of critical supervision in policing
should be random audits of at least a few of each officer's videos each quarter,” but no reference
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg
8 of 13
9
to any “standard” is set forth (Ex. A at 15). Mr. Corsentino relies on these standards to render his
opinions, but any such standards are not the product of identifiable and reliable principles and
methods. Furthermore, there are no indications in the Report, the opinions are subject to any sort
of peer review or have attained general acceptance in the relevant community.
The Report also provides no indication as to how any of the opinions assist the trier of fact
to determine the issue of Haferman’s probable cause determination. The Report criticizes areas
such as the failure of Haferman to activate his body-worn camera on a number of occasions (Ex.
A at 12), and a Lieutenant’s apparent berating of a citizen who made a complaint about Haferman,
unrelated to any of the pending DUI matters (Ex. A at 12), but there is no reasoning provided as
to how these opinions would assist the trier of fact, with respect to Haferman’s probable cause
determination. The Report, in fact, does not even address the specific arrest of the Plaintiff. Any
such opinions should therefore be precluded. Specht, 853 F.2d at 810.
2. Corsentino’s Opinions Should be Precluded on Relevancy Grounds as Posing
Potential to Confuse a Jury.
Even if proffered expert testimony meets these “reliability” criteria, this Court also must
determine such testimony is relevant to the case, because “the expert testimony must ‘fit’ the facts
at issue, requiring a valid scientific connection between the testimony and issue sought to be
proven.” Magdaleno, 5 F. Supp. 2d at 902. The reliability focus is on the proposed expert’s
principles and methodology, not on conclusions reached. Daubert, 509 U.S. at 595. An expert
cannot simply tell the jury what result it should reach without an adequate explanation of
appropriate criteria for that opinion. See United States v. Richter, 796 F.3d 1173, 1195-96 (10th
Cir. 2015).
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg
9 of 13
10
The premises for Plaintiff’s allegation of a constitutional violation, relies on actions of Mr.
Haferman’s determination of probable cause. It is, therefore, necessary for Mr. Corsentino’s
opinions to provide an identifiable nexus between his criticisms of FCPS, and Haferman’s
probable cause determination. Merely identifying alleged flaws in the administrative functions of
FCPS, however, is both insufficient and irrelevant to establishing the City’s constitutional liability.
In particular, allowing opinions such as the City failed to follow minimal standards of supervision,
or failed to audit body-worn cameras according to some, unidentifiable schedule, without
consideration of the Haferman’s actions, does not consider the need for Plaintiff to establish a
direct and causal link between any specific custom or policy and the violation alleged, or even the
City’s culpable state of mind. Jenkins 81 F.3d at 993.
Allowing Mr. Corsentino’s opinions, also risks impermissibly establishing liability based
on respondeat superior, without establishing an underlying constitutional violation. “Municipal
liability requires an underlying constitutional violation.” Jurinsky v. Arapahoe Cnty. Dep’t of
Hum. Servs., 2024 U.S. App. LEXIS 25487, *10-11 (10th Cir. 2024), citing Burke v. Regalado,
935 F.3d 960, 998 (10th Cir. 2019). “A core principle of Monell liability is that municipal entities
are liable for only their own actions and not vicariously liable for the actions of their employees.”
Jurinsky, supra, citing Crowson v. Wash. Cnty., Utah, 983 F.3d 1166, 1191 (10th Cir. 2020). “But
‘[b]ecause municipalities act through officers, ordinarily there will be a municipal violation only
where an individual officer commits a constitutional violation.’” Jurinsky, supra, citing Burke,
supra.
Mr. Corsentino’s opinions criticize the actions of Sergeant Heaton and Corporal Bogosian.
(Ex. A at 22-23). But, neither are defendants in this matter and even if they were, the opinions
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg
10 of 13
11
establishing liability against the City, based on their actions (or the actions of others), is improper
and should be precluded.
D. Corsentino’s Proposed Expert Opinions must be Excluded by the Court as Improper
Legal Opinions that Inappropriately Invade the Province of both the Court and the
Jury.
Mr. Corsentino generates his opinions against the City of Fort Collins, without considering
the relevant constitutional standards related to municipal liability. By doing so, the jury is
effectively instructed that the criticisms outlined by Mr. Corsentino, create the standard by which
the City should be judged. For example, when Mr. Corsentino opines the City failed to adhere to
minimal supervisory standards, he does so without consideration of deliberate conduct, causal
nexus, or even identification of a custom, policy or practice. Allowing Mr. Corsentino to opine
the City failed to meet some unidentified standard, or that any such failures stem from the actions
of Sergeant Heaton, Corporal Bogosian, or any other individual associated with FCPS, effectively
dilutes Plaintiff’s burden to something which is more akin to a negligence or malpractice standard.
By implicitly instructing the jury on an incorrect and “lower” standard, the function of the jury is
usurped and the Court’s function in instructing on the proper Constitutional burden is overtaken.
Any such approach is improper, and should be precluded.
In Specht, the Tenth Circuit held “a witness cannot be allowed to give an opinion on the
question of law,” and “in order to justify having courts resolve disputes between litigants, it must
be posited as an a priori assumption that there is one, but only one, legal answer for every
cognizable dispute.” Specht, 853 F.2d at 807. The Tenth Circuit went on to explain that to allow
anyone other than the judge to state or even opine on the law would violate this basic concept. Id.
In examining Rule 704, the Tenth Circuit explained:
Case No. 1:23-cv-01339-RM-TPO Document 86 filed 12/04/24 USDC Colorado pg
11 of 13
12
While testimony on ultimate facts is authorized under Rule 704, the
committee’s comments emphasize that testimony on ultimate questions of
law is not favored. The basis for this distinction is that the testimony on the
ultimate factual question aids the jury in reaching a verdict; testimony which
articulates and applies the relevant law, however, circumvents the jury’s
decision-making function by telling it how to decide the case.
Specht, 853 F.3d 808; see Oakland Oil Co. v. Conoco Inc., 144 F.3d 1308, 1328 (10th Cir.
1998) (“Generally, an expert may not state his or her opinion as to legal standards nor may he or
she state legal conclusions drawn by applying the law to the facts.”); A.E. ex rel. Evans v. Indep.
Sch. Dist. No. 25, 936 F.2d 472, 476 (10th Cir. 1991) (“However, an expert may not state legal
conclusions drawn by applying the law to the facts.”) Mr. Corsentino’s opinions are inappropriate
under Specht, and should be precluded.
IV. CONCLUSION
For the foregoing reasons, the City of Fort Collins, requests the Court: enter an Order
directing that a Daubert hearing be conducted with respect to the proposed expert testimony of
Plaintiff’s expert witness Dan Corsentino; following that Daubert hearing, strike all of
Corsentino’s testimony from any trial in this matter and, enter all such additional relief as the Court
deems just and appropriate.
Respectfully submitted this 4th day of December 2024.
