But as an outsider, its really not normal for agents of the state to detain people without legal basis. much less deliberatly make sure they can't be found. (citizen or not.)
You as a US citizen are not required to carry ID, so being arrested on the spot for not having proof of citizenship is grossly authoritarian.
Not to mention shooting someone in the street.
