Can a Peace Officer request a polygraph examination of a complainant?

A Peace Officer cannot request a polygraph examination of a complainant because such examinations are generally considered unreliable and can infringe on the rights of individuals. The practice and legality surrounding polygraph tests are complex, and there are ethical concerns about using polygraph results in investigations or legal proceedings.

In many jurisdictions, there are specific rules and laws that prohibit law enforcement from compelling individuals to undergo polygraph examinations without their consent. Requiring a complainant to take a polygraph could also create a barrier to reporting crimes, as it could intimidate victims or deter them from coming forward altogether.

The other choices present scenarios where a polygraph might seem permissible, but in practice, these considerations are not aligned with the legal framework that governs interactions between law enforcement and complainants regarding such sensitive procedures.
