They would never have the G20 in LA, and if they did, we would have actual Military servicemen patrolling the streets.
Actually, the "Posse Comitatus Act" used to "limit the powers of the federal government to use the military for law enforcement." However, "On September 26, 2006, President Bush urged Congress to consider revising federal laws so that U.S. armed forces could restore public order and enforce laws in the aftermath of a natural disaster, in the wake of Hurricane Katrina."
Which is bullshit, of course, 'cause our rights are dying like flies.
How about civil disobedience? Instead of rioting and shit, how about a peaceful protest?
