Here We Go Again At Post Office
Seven dead after Calif. postal shooting spree
It has to be asked at this point: what is wrong with postal workers? Too many shootings have occurred not to wonder what is missing in the interview process that so many people who are willing to not just off themselves, but groups of other people are winding up working there?
I don't care what they say, their work is not so incredibly stressful that it's going to lead people to just snap. Most of the sorting, etc. is done by machine, most stamps are purchased at somewhere other than from a postal employee over the counter, and most priority packages are being sent by private courier services. They're union employees, so it's not like they don't have job security and benefits. There's no good reason other than that the Post Office is going out of their way to hire the mentally unstable.
If there has to be gun control of any kind, it looks like prohibiting any one who works or has worked there from owning one is the best place to start.
