since she was jaywalking she has a valid arrest. same EXACT THING happened to me but in my case cop did not witness and it was an “intersection” giving me a loophole in jaywalk charge. I was on foot with my ID locked in trunk of my car. Told cop that but argued with him about my detainment...started filming...refused to sit on curb...got arrested.Had to get an ACLU-type lawyer to pursue a 1983 case.We shall see. BTW...conservative ruling set us up for just this kind of thing....Its all because of that ruling above.
They say it’s about safety but it’s really about them being able to stop anyone they want at anytime.
It’s a police state, get used to it.
