>This isn't how it works in the United States at least. The police are allowed to lie to you, your lawyer, the media, anyone they want to, as long as they are not under oath.

That seems like you're playing semantics.

A contempt charge is a type of criminal charge. My contention is that if a lawyer, during discovery, asks the police a question like "did you analyze the data" and they lie they'd face issues.

So it looks like we're in agreement :)
