Uh, if I shoved someone in front of a 40mph 7000ton mass, it would done completely with the expectation of death. A case could be made it's premeditated, let alone attempted.
Atlanta is one of the worst fucking places I've ever been. It's probably worse than Memphis overall and I lived there when it was the murder capitol (in fact, I've been in pretty much every murder capitol in US in the 90's). You think being on MARTA with a shitload of electronics is bad, try installing a goddamn alarm system in the federal housing projects. Most times I've been shot at was because I was white and in a shitty ghetto (ironically trying to help their fucking grandmothers). Not a hate crime though.
Looked it up, turns out they've dozed all those projects in Memphis and replaced them with very nice looking townhouses. Problem is, the people didn't change. It's like smearing shit on a 10th century tapestry, it just doesn't make sense. Just because it doesn't look like a favela, doesn't mean it isn't one. IMO, that's actually dangerous because not being from Memphis, I was still pretty adept at determining the "red alarm" areas, but if they all look like Germantown it makes it a bit harder.
Basically, if you are in any metropolitan area in the south, and you don't see any moon faces around, you are in the ghetto. It's not racist, it's just a fact. BTDT.
Only time I ever carried more than a pistol as a civilian was when I had to fix alarms in Memphis. I had an Uzi in the toolbox. A few times I paid a guy to sit in my truck with an AK. He was supposed to be my wire rat but I had to repurpose him into a bodyguard. They usually quit the next day. I'm not making this shit up. Luckily they never opened an office in Atlanta.
