Aliens must have shown us what happens when you shoot-to-kill looters and violent protesters.
It must be horrible, because how else can you explain the State Police and SWAT not firing on them.
People were NOT uncivil and were quite experienced in San Francisco back in 1906.
After the great earthquake, they summarily executed looters right out in front of the place, against a wall. And hung a sign around the neck for effective public display.
I guess that doesn't work when everybody on the planet has a video camera in their phone.
