I came across this link to the Immigration Legal Resource Center (in an article from The Hill of all places) with downloads for know your rights cards, specifically for if you’re harassed by ICE goons. It’s all good advice regardless of what law enforcement you’re dealing with. I’ve already put an order in with a print shop and may have more made with more generic language later. Anyway, if anyone else is interested in a little Know Your Rights activism : https://www.ilrc.org/red-cards-tarjetas-rojas
