Even if you chose to argue statistical frames, as I'm seeing so much in this thread, you're not factoring the ripple effects that must surely be caused by the knowledge that official agents of power view you and your family as inherently, or very potentially inherently, dangerous. It doesn't take a critical mass of groundless violence (even if that mass does indeed exist)-- but just some of it, left unaccounted (or even defended) by those same official agents. Such a message is bound to resonate broadly and cause what should be a comprehensible outcry from, for example, the mother quoted in this article. I'm saying that you might consider the nonchalant (at best) response to such violent incidents.
