Crossing state lines, with parts

With probable cause if I recall reading that correctly. I was actually surprised at that, because most other states were already that way.

They do not need probable cause...they can just make it up. If you refuse, you just might suffer a couple of "self inflicted" gunshot wounds to the back, or might drown yourself in a toilet while "resisting arrest".

There is a reason cops react to cameras like cockroaches to floodlights.
