You don't get it at all. Reagan released a ton of homeless, of "special to the family," and whatnot and then ...... their caretakers died.
Before that, these "special family" met other "special family" and freaking reproduced because their caretaker family, which owned plenty of guns, was getting older and dying.
Well this isn't Reagan's 40s and 50s where family still lives close and those crazies who still lived in the old home place had Mom and Dad's old house, their guns, and they had kids they're going to raise chaotically.
So you have crazy people raising kids with plenty of weapons nearby........ what could possibly go wrong after Reagan?
