One should never forget that the BG ,in high probability, will wear some sort of armoured chest protector, which I strongly feel that it should be banned except for LEOs & Military use
So I shouldn't have one because the BG might get one? I guess you could make the same argument about having access to a gun. "Bullet Proof" vests are generally used and were conceived as being defensive implements. I am retired LEO but would hate to see the day that only cops or soldiers could lawfully avail themselves of an armored chest protector, leaving only the law-abiding citizen without an option to protect himself of same, should he ever want one.
Like guns (and knives in London), banning the ownership of same to law-abiding citizens will only mean that law-breakers will have them-and that axiom, sadly, applies to chest protectors.
