I find it interesting in the US that we hold lawyers to the high standard of no lying, while law enforcement officers are given more latitude, esp in interrogation situations.<p>Seeing it in TV shows and movies, which often have officers and detectives lying about knowledge, evidence, other witness statements, all to get info, I assumed that it was fictional. In many cases, though not all, it appears to be allowed within limits in real life. See, for example, <a href="https://www.google.com/amp/s/www.adamsluka.com/amp/can-the-police-lie-to-me.html" rel="nofollow">https://www.google.com/amp/s/www.adamsluka.com/amp/can-the-p...</a>.<p>This doesn't mean all cops are liars, and they still shouldn't commit perjury, but it's an interesting comparison to me. I guess it's a reflection of the advocate/adversary approach that is often a part of the legal process.
