That is a ridiculous response. For one, the economy is in the crapper, so I would recommend holding down whatever job you are lucky enough to have. It would seem that body armor of some kind if becoming more prolific, as it is often heard through reasonably credible sources.

Something else to keep in mind is that gangs in the military and "bad guys" with military back grounds are becoming MORE commonplace, not less.

Here in Houston, the bad guys have been waiting at banks, grocery stores, and drug store parking lots for a likely victim to come up, then either accost them on the spot or following them home. I think this type of the thing has been happening all over more frequently, but yesterday in Ace Hardware, there were two random people, both of whom knew someone that had been a recent victim of this kind of violent crime.
If you don't have something relevant to add to the discussion, then why reply at all?? I come across these all the time. Someone asks a question and someone else flippantly throws out "get a dog" or "move", etc...
