MEMORANDUM OPINION AND ORDER
Before the Court is Plaintiff Karolina Obrycka's motion in limine in which she seeks to bar certain aspects of the expert opinion testimony of Matthew J. Hickman, Ph.D., pursuant to Rule 702 and Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 113 S. Ct. 2786, 125 L.Ed.2d 469 (1993). If permitted to testify, Defendants anticipate that Dr. Hickman would offer expert testimony on the lack of scientific validity in the study conducted by Plaintiff's expert witness Dr. Whitman. As explained in detail below, the Court grants in part and denies in part Plaintiff's Daubert motion as to Dr. Hickman.*fn1
On April 30, 2007, Plaintiff Karolina Obrycka brought a five-count Complaint alleging that Defendants City of Chicago and former Chicago police officer Anthony Abbate, Jr. violated her constitutional rights in relation to an incident on February 19, 2007 at Jesse's Shortstop Inn in Chicago, Illinois and the subsequent investigation into that incident. In particular, Obrycka maintains that the de facto policies of the City of Chicago -- through the conduct of members of the Chicago Police Department's ("CPD") Office of Professional Standards and the CPD's Internal Affairs Division in impeding and interfering with the investigation of police misconduct, including police brutality -- deprived her of her Fourteenth Amendment substantive due process liberty interest in bodily integrity. See Monell v. Department of Soc. Servs. of New York, 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978).
Obrycka seeks to establish her Monell claim by presenting evidence that the City has a well-settled, widespread practice or custom of impeding and interfering with police misconduct investigations. Moreover, Obrycka argues that there is an attendant "code of silence" that exists within the CPD, whereby officers conceal each other's misconduct in contravention of their sworn duties. Obrycka maintains that this de facto policy and the code of silence are evidenced and caused by the CPD's failure to: (1) sufficiently investigate allegations of police misconduct;
(2) accept citizen complaints against police officers; (3) promptly interview suspected officers or take witness statements and preserve evidence; (4) properly and sufficiently discipline officers; and (5) maintain accurate and complete records of complaints and investigations of misconduct. Obrycka also contends that the CPD fabricates exculpatory evidence or destroys evidence when investigating citizen complaints against its police officers. Further, Obrycka maintains that this de facto policy and the code of silence encourage Chicago police officers to engage in misconduct with impunity and without the fear of official consequences.
In support of her Monell claim at summary judgment, Obrycka presented the testimony of Dr. Steven Whitman, who is her expert statistician. Dr. Whitman opined that based upon his statistical analysis of the rates of sustained findings in force-related complaints for Chicago police officers from 1999 through 2004, as well as specific data rates for the 25th District -- where the incident at issue occurred -- and the 11th and 20th Districts -- in which Defendant Abbate had worked in the five years prior to 2007, the sustained rates for force-related complaints against Chicago police officers over the eight years prior to 2007 were statistically significantly lower than the national average sustained rates reported in the Bureau of Justice Statistics "Citizens Complaints About Police Use of Force Report" for the national average for all departments (8%) or the national average for larger departments like Chicago (6%). More specifically, the average sustained rate within the CPD was as low as 0.5% in 2004. Dr. Whitman also observed that in the 25th District from January 2005 through February 2007, not one of the 147 excessive force complaints was sustained, and in the 11th and 20th Districts, the sustained rate was only 1.2%.
"The admissibility of expert testimony is governed by Federal Rule of Evidence 702 and the Supreme Court's opinion in Daubert[.]" Lewis v. CITGO Petroleum Corp., 561 F.3d 698, 705 (7th Cir. 2009). "The district court functions as a gatekeeper with respect to testimony proffered under Rule 702 to ensure that the testimony is sufficiently reliable to qualify for admission." Mihailovich v. Laatsch, 359 F.3d 892, 918 (7th Cir. 2004) (citing Kumho Tire Co. v. Carmichael, 526 U.S. 137, 147, 119 S. Ct. 1167, 143 L.Ed.2d 238 (1999)); see also Lapsley v. Xtek, Inc., ___ F.3d ___, 2012 WL 3055865, at *1 (7th Cir. July 27, 2012) ("The purpose of [the Daubert] inquiry is to vet the proposed testimony under Rule 702's requirements that it be "based on sufficient facts or data," use "reliable principles and methods," and "reliably appl[y] the principles and methods to the facts of the case.") (quoting Fed. R. Evid. 702)). Whether to admit expert testimony rests within the discretion of the district court. See General Elec. Co. v. Joiner, 522 U.S. 136, 142, 118 S. Ct. 512, 139 L.Ed.2d 508 (1997); Lapsley, 2012 WL 3055865, at *6 ("we 'give the district court wide latitude in performing its gate-keeping function and determining both how to measure the reliability of expert testimony and whether the testimony itself is reliable'") (citation omitted). "The proponent of the expert bears the burden of demonstrating that the expert's testimony would satisfy the Daubert standard" by a preponderance of the evidence. Lewis, 561 F.3d at 705.
Under Rule 702, "[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 sufficient facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the expert has reliably applied the principles and methods to the facts of the case." Fed. R. Evid. 702; see also Ortiz v. City of Chicago, 656 F.3d 523, 526 (7th Cir. 2011).
District courts employ a three-part analysis before admitting expert testimony: (1) the expert must be qualified as an expert by knowledge, skill, experience, training, or education;
(2) the expert's reasoning or methodology underlying his testimony must be scientifically reliable; and (3) the expert's testimony must assist the trier of fact in understanding the evidence or to determine a factual issue. See Myers v. Illinois Cent. R.R. Co., 629 F.3d 639, 644 (7th Cir. 2010). "The purpose of the Daubert inquiry is to scrutinize proposed expert witness testimony to determine if it has "the same level of intellectual rigor that characterizes the practice of an expert in the relevant field" so as to be deemed reliable enough to present to a jury." Lapsley, 2012 WL 3055865, at *1 (quoting Kumho Tire Co., 526 U.S. at 152).
