Reading this article I can't help but think about a guy who is a "powder keg" waiting to explode like that guy yesterday. (Too soon?). He seems to feel slighted with the world and has a fragile mentality that could set him over the edge. He has failed to commit suicide on several occasions, probably because he was too scared to go all the way through with it. God forbid does a suicide by cop and takes out a few people along the way.
Hopefully I'm wrong, but he seems very unstable. Hope he's getting the help he needs.
