While I am sympathetic to the Mother and think it is kinda brave to push this and show her son staggering around and pounding on stuff randomly (not hide that part of the video), I can't help thinking that if the races were reversed, the victim's Mom would not have faith in the judicial system and would have returned home to quietly mourn her son knowing that if a black man gets that drunk and runs around the way he did, he is going to get punched like that or worse.
The video also doesn't show an incident that happened prior to the Jones encounter where Szabo was making so much noise that a neighbor came down and they had a confrontation of their own.
Also, while it does look like Jones is the aggressor, it wasn't a multi-punch attack - he confronted him, kind of punched as he ran over him, seemed surprised that he went down like that, and retreated to his car. Not a good look at all, but not a brutal attack either, which is probably why Jones isn't being charged as the Mother desires.
