In determining whether expert testimony on the use of force by a police officer is properly admissible under the appropriate standard, we note that "[a]s a general proposition, the 'objective reasonableness' standard may be comprehensible to a lay juror. On the other hand, any 'objective' test implies the existence of a standard of conduct, and, where the standard is not defined by the generic--a reasonable person--but rather by the specific--a reasonable officer--it is more likely that [federal rule of evidence] 702's line between common and specialized knowledge has been crossed." Kopf v. Skyrm, 993 F.2d 374, 378 (4th Cir. 1993) (analyzing plaintiff's claim that court improperly excluded expert testimony concerning defendant's use of non-deadly force in effecting arrest). In Kopf, the United States Court of Appeals for the Fourth Circuit stated that "[w]here force is reduced to its most primitive form--the bare hands--expert testimony might not be helpful. Add handcuffs, a gun, a slapjack, [M]ace, or some other tool, and the jury may start to ask itself: what is [M]ace? what is an officer's training on using a gun? how much damage can a slapjack do? Answering these questions may often be assisted by expert testimony."

Public employees are “the members of a community most likely to have informed and definite opinions” about a wide range of matters related, directly or indirectly, to their employment. Courts balance the First Amendment interest of the employee against “the interest of the State, as an employer, in promoting the efficiency of the public services it performs through its employees.”...42 U.S.C. § 1985(2) protects expert witnesses...because individuals working in law enforcement "are often in the best position to know" about the occurrence of official misconduct, "it is essential" that such well-placed individuals "be able to speak out freely" about official misconduct......
