There is no possible way such a force can be hidden. Such a force requires massive amounts of TRAINING to become a cohesive, effective force. At the barest minimum they need Co-strength organization in many places throughout the country. Any leftie who thinks they can just scoop up a bunch of black gangbangers from Philly and start subjugating the region needs to get off the dope. Just around here, some calls to some PD friends and ten-minute trips to the local gun clubs (yes, I said clubs — as in plural) will get the word out to a number of well-armed individuals who are very, VERY competent at their craft. And note that I didn’t mention handguns — we have ALL kinds around here.
And I haven’t even mentioned official means of putting down such uprisings such as County Wide Assist. Our cops know how to deal with large groups of rioting, armed minorities. They CAN handle gangbangers with automatic weapons — they’ve had to do it before.
That’s not to say that I don’t plan to increase my preparations.
Thing you got to remember is that every one of these “recruits” is American. That means US.
