I think the common thread with all such scams is creating a sense of urgency and high stakes. I'd generalize what you said though: if something involves a legal process or supposed pre-existing correspondence, anything crucial will happen in writing or in person and they'll be able to specifically provide you with the dates and details of anything they claim to have on you. Personally I haven't had fake police calls yet (well, except for one Eastern European lady in a call center using a fake mobile number while pretending in broken English to be from INTERPOL, whom I immediately hung up on) but I have had calls about contracts I supposedly agreed to over the phone and was going to have to pay for either way but could now immediately agree to a compromise so I wouldn't have to pay the full amount owed but order (this time for real) something else or some contrivance like that. Of course calling back was not an option because this was already about to hit collections and they had recorded my previous (non-existant) call but couldn't play it back to me right now. It was all a bit ridiculous but I still felt a bit unnerved until I called my lawyer and learned that even if everything they said were true the contract as described would be invalid and any claims would have to be sent in writing before anything actionable even happened on my end.
