Plain and simple, he didn't deserve to die, nor get socked like he did. That was just some cheap ass cowardly shit. I don't know how any of you can defend that shit. You have to remember that he's an older man, old people do wierd shit like that all the time. His intentions were just to obviously make the city look nicer by adding plants and watering them. As a young person, you should know better than to assualt a man like his type. This man was probably unaware of the annoyance he caused others because he's stuck in his own little retired mindset. In his own mind, he thought he was doing the community good. You gotta THINK before messing with older people like that because they just start loosing awareness over time on how society reacts to shit like that.
Best thing to do is call the fucking city and see if what he's doing is legal.
