Well thanks for your concern man, but i wouldn't say i have trauma by it. I mean like i said, i didn't know the guy personally, plus id imagine actually seeing it, rather than just hearing it would be far worse, obviously. But another thing, this isn't the first time their has been a shooting/killing near my house.
A few years ago a man down the street from me shot his wife point blank outside their house. It was in the afternoon too! According to the paper, they got into an argument, she ran outside cause he got a gun, halfway down the street he gunned her down from behind, as she was running. He killed her.
I remember driving by the house the very next day and her blood was stained on the sidewalk still... Shits sad. As for the motive of the gunshot i actually heard, im not quite sure. Police did suspect it to be drug related though.
As for yourself (where you live) be careful man. People are damn crazy.
