I hate to admit it as much as the next guy but it can and will teach you to get out of sticky situations. It literally just saved my balls. If you are hitting the streets at all in the USA you should be familiar with terminology like “terry stops”. Seriously. Watch some cop watch content.
I’m not sure what your point is here. OP asked if cops can make things up to hold you, I said perhaps. A worker learning to talk like a lawyer or reading Lenin is irrelevant when you’re arrested.
Speaking like a lawyer =/= being a lawyer. Unless you somehow have read decades worth of law, cases, and understand when to talk and when not to talk, just ask for a lawyer and spare yourself prison time.
