This civil rights action arises out of an October 23, 2020 traffic stop involving Plaintiff, Kary Jarvis and Daytona Beach Police Department officers Marville Tucker and James Mackenzie. As a result of the traffic stop, Plaintiff was injured and filed a complaint alleging false arrest.

Defendants, City of Daytona Beach as well as Marville Tucker and James Mackenzie filed respective _[Daubert](https://www.law.cornell.edu/wex/daubert_standard)_motions to exclude the testimony of Plaintiff’s expert [Thomas Tiderington](https://expertwitnessprofiler.com/expert-witness/Thomas-Tiderington/1552463).
