How did the very agencies that protect us (FBI ATF ETC...)not pck up on this kid
Without banning so many kinds of guns that self defense would be virtually useless (and many decent sportsmen would be very, er, up in arms) it’s impossible.
Situational awareness needs to pick up. Sheeple can have such a super expectation of safety they never think to what if the worst (or even bad) occurs. A shooter like this is unlikely to show himself, but how about your common street mugger? Shouldn’t people be readier for that? And not just count on some set of exalted officials to guard them? Police may occasionally nab a malefactor red handed but usually they are only there to pick up the pieces.
