Whitfield v. Riley, 2021 U.S. Dist. LEXIS 166498 (E. D. La. 2021)

The district court determined the experts' reasoning or methodology "fits" the facts of the case and would assist the trier of fact to understand the evidence, i.e., whether it is relevant. Daubert, 509 U.S. at 591. An expert's testimony is not relevant and may be excluded if it is directed to an issue that is "well within the common sense understanding of jurors and requires no expert testimony." Vogler v. Blackmore, 352 F.3d 150, 155 (5th Cir. 2003).The Court held that Howard mdade improper conclusions about the practices of the NOPD. So, ehile his testimony will be permitted at trial, the Court notes that Howard should be placed on notice of his proper role — an expert lending his qualifications to assist the jury in its understanding of firearms and gunshot residue. As for Peters, the Court found that Peters's exper report properly recited the predicate facts upon which he relied when forming his conclusions, rather than recommending how the trier of fact should resolve any disputed facts, therefore his testimony is valid.
