He wasn't arrested simply for calling 911, though. It's an undeniably shitty situation, but based on his own account, if he and his friend simply got the cellphone back, said "thanks", or even just shut up and went home, we most likely wouldn't be arguing about this right now.

I have no idea what it would take to curb a significant portion of this sort of overreach, but it is worth being stripped naked and thrown in solitary confinement? You tell me.
