Cop Car (2015)

Factual error: The Sheriff clears all other police traffic on a specific radio frequency so that he can "secretly" chat with the two young boys. Of course, secrecy is crucial to the Sheriff's motivation all throughout the movie. However, police radios have extraordinary range, and police radio channels are constantly monitored by neighboring police forces, by other first-responder agencies, by civilian police scanners, and even by the news media. The Sheriff should surely know that it is impossible to conduct a "secret" or even "private" conversation over police radio.
