BTW, not all militias identify themselves as anti-govmt, nazis, etc. Some declare that their goal is supporting local law enforcement weakened by budget cuts.
After all, we have volunteer firefighters, guardian angels (unarmed) paroling street in troubled neighborhoods, maybe militias of local pre-screened community members is a next new thing.
I personally don't see a need for armed citizens getting together, but then again, I don't live on Mexico - Arizona border where illegals and drug smugglers are robing and killing local farmers.
