Glass v. Anne Arundel County, 38 F. Supp. 3d 705

Glass sues County and officers under 42 U.S.C. §1983 for alleged constitutional violations arising from a traffic stop by Collier; CAD records and stop duration are disputed.
Glass’s version: Collier abruptly cutoff, blocked path, displayed gun, demanded license/registration, and engaged in contentious conduct during a 20–30 minute stop; Glass later called 911 to confirm Collier’s status.
Collier’s version: Glass followed closely, Horn blow by Glass, Collier initiated the stop, identified himself, and positioned his SUV to shield from traffic; he contends he acted lawfully.
An expert report by Gregory Russell analyzes braking distances and timing to support Glass’s claim of dangerous conduct by Collier; Russell relies on four factual assumptions.
In 2011 Glass was acquitted of the traffic ticket at a local trial; the current suit targets Collier and other officers under §1983, with a bifurcated, stayed County claim.
Court grants summary judgment in part: Collier’s fabrication-of-evidence claim (count two) is dismissed, and Campbell? (Collier) summary judgment denied on false arrest claim (count one).

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Collier’s stop violated the Fourth Amendment	Glass asserts he was followed closely and unlawfully detained.	Collier contends stop was supported by reasonable suspicion.	Genuine dispute of material fact; summary judgment denied for count one.
Whether Collier fabricated evidence causing deprivation of liberty	Glass argues Collier’s typed notes and statements caused detention and prosecution.	No causal link shown between fabrication and deprivation.	Count two granted; fabrication evidence did not cause deprivation.
