The perp may have been, angry and frustrated, depressed and lonely, sad and on Methadone, full of rage at society, not getting what he is “entitled” to receive as benefits. This can push a man over to despair and cause him to just to lash out, kill a more privileged whitish man but even only we could have “saved” this poor victim beforehand, maybe he would have just played that “knockout” game instead...oh woe is me, why can’t we solve all of societies’ ills? Oh the poor diddums, what must have been going trough his tortured mind before he committed this desperate act. We need to find him, heal him, pay him and let him appear on talk shows, explaining his case...
I don’t know he most likely is a crazy person, delusional in some way, but from the still shot I saw he doesn’t look particularly young, or crazy, or homeless.
He looks like a very ordinary, middle aged, middle class black guy.
But you know I could be wrong, that’s just looking at one picture of the guy from some security camera so it’s not even at a very good angle.
