The feds draft people from all sorts of other agencies to fill the ranks of FEMA. They seldom get the same people twice. Even when they get someone competent, that person is surrounded with incompetents so they are effectively neutralized. Contrast that with your average guy. Take me for an example. I have worked at every level of law enforcement. I have a pretty good handle on the capabilities of all. Most local law enforcement folks are just as worried about a fed takeover as you and me. They aren't about to let that happen. Martial law? Even if the entire military, trigger pullers, clerks and jerks, military police, truck drivers, etc, were to be teld to enforce martial law, we would outnumber them by hundreds to one. Then you have the fact that according to the latest survey, the military is on our side by 3 to 1, and you have conditions where they would not use force against the American people. The threat of martial law is bogus. Perhaps FEMA could take over a city, even a big one, but the federal government is far too incompetent to take over the country. Besides, We Won't Let Them. -if you get my drift.
I suspect there will be a good deal of civil disorder in the cities. If you live there, consider getting out before 11/04. If you can't get out, be prepared to ride it out and to defend yourself and your loved ones. The good guys will win this one.
Am I worried about BHO? Of course, but again, he can only become dictator if we let him. Many, like me are committed to preventing that from happening. (OK, I probably just made his enemies list). But I don't care. I'll die on my feet, not on my knees.
