Just Got Back From the Police Station.

Yeah man, the guy sounds nuts. Please remember though that there are even way more insane people than that running around. Some carry guns etc....
It's best to just avoid confrontation at all cost. You actually got lucky that nothing worse came from this. I just move over and let these Nutballers go around me and never see them again. You can do what you want but I recommend you rethink how you handled this whole situation.
