It might be better to station these checkpoints where real crimes occur daily. Places like legislatures, courts, central banks, most government agencies and major party political conventions immediately come to mind. In these settings it’s said people are usually high on OPM (other peoples’ money).
I’m curious about something. I understand that not responding to police questions gives them nothing to work with. But what if the police ordered a protester to show some ID or to hand over their smart phone? I assume that no one carried ID, but smart phones do carry some identifying information and more and more police departments now have readers that plug into the USB port and can extract the contents of phones. What about that situation?
First, Mark, I'm sorry to disappoint you but no one got tasered.

I thinked I'd just stick to the silent treatment to the bitter end. They should back off if they know they have no legal grounds to stop you.
