The only issue with the military stuff is that it's bulky and one would suspect that folks would have issues wearing it and trying to do their jobs....

That's why LE wears soft body armor under their uniforms. Lighter and less restrictive. We only wear the "military" stuff when we are going on raids when rifles totting bad-guys could be in the picture.....

I could only imagine watching some of the fat dudes/chicks wearing the bulky military stuff and dropping out at a checkpoint due to dehydration..... then suing the GOV....
