I am going to throw something out there, to see if smiles are inspired.
Whenever I find someone willing to listen to "anarchist" perspectives I take out my old fashioned cell phone with the flip top, and the small antenna that sticks out the top.
I have a routine that goes like this:
"What would you do if you found out that there was a State next to your State (Arizona while I am in California) and in that State now, right now, there are these new Self Defense Weapons Legal for anyone to have and use. Got it?"
"When you use it there is a recording of the event being made and uploaded to the internet for viewing by other interested people."
"This is not in your State."
"This is in the State next to your State."
I keep waiting for a response.
"OK, go ahead."
"You feel threatened, the recording starts, you aim the device, you shoot, and the person that makes you feel threatened is immobile for 1 hour, no other harm is done to the person who makes you feel threatened."
I can see the wheels turning at that time, but before they speak I add:
"Do you allow it in your State?"
