Yup. Tough to defend the ex-cop on this one. If you can press your gun right up against the back of someone's head, you can just as easily shift it 8" diagonally and shoot them in the very arm that is allegedly gripping your taser.

I can't speak for APD, but in BPD (which is a cluster B personality disorder), up to 30% of patients with the disorder reported no abuse of any kind during their childhood.

So there is some evidence that it is nature for some individuals. It's politically incorrect to say that these days (especially here on reddit), but the wonderful thing about science is it doesn't care what your ideology tells you is true.

Anti-science folks, of course, will still find any sliver of doubt to cling to their beliefs that everything bad with the world can be blamed on "bad parenting".
