Kansas illegally searched out of state drivers. Pressing the question… why would you ever want to go to Kansas.
… quick article highlight, it turns out most drivers targeted were just passing through to visit states without a police force trained to violate the constitution
But the ACLU helped fight the case all the way to the US Federal District Court on behalf of many motorists who doubtlessly never wanted to go back to the state again, even if to protest their rights in court
If any cop asks you if you’re doing something illegal… immediately ask for a lawyer. You’re not obligated to answer any questions or give them any information at all. this obligates them to either cease questioning you and let you go, or arrest you while they fetch a lawyer. they’re not going to do that over a traffic stop where they have nothing else.
Further, if they continue pressing or asking questions, or anything they learn (or “Learn”) from that questioning is tainted and inadmissible; and there’s a solid argument for “they didn’t have probable cause before asking questions, I asked for a lawyer and they said that gave them probable cause” will invalidate anything turned up from a search.
