For what reason may a Peace Officer not dismiss a complaint according to regulation?

A Peace Officer may not dismiss a complaint on the basis that the complainant does not take a polygraph. This is because the decision to pursue a case should not rely on the complainant's willingness to undergo such a test, which is often voluntary and not a requirement for moving forward with an investigation or prosecution. Polygraphs can be unreliable and do not guarantee truthfulness; therefore, dismissing a complaint based solely on the absence of a polygraph examination would undermine the officer's obligation to investigate complaints thoroughly.

The other factors, such as lack of evidence, witness statements, or a suspect having an alibi, may legitimately influence the decision to proceed with a case based on the available information and circumstances. However, the inability to compel a complainant to take a polygraph as a condition for pursuing justice underscores the importance of ensuring that all complaints are taken seriously and investigated properly, regardless of whether the complainant participates in polygraph testing.
