As probably this forum's premier gun enthusiast (and one who gets annoyed when the gun hobby is misrepresented on this forum), I am surprised to see you use this term.nonlethal rubber bullets.
I thought rubber bullets were now described as 'less lethal'? Because I remember a number of cases over here in the UK during The Troubles, when rubber bullets were discovered to be very lethal indeed. They're nonlethal in the same way a kitchen knife is; no, they're not designed to kill, but they're still quite capable of it. I mean, yes, it was mostly when headshots occurred, true, but that's why 'less lethal' replaced 'nonlethal', because they're safer than regular bullets but still, well, lethal. It was part of the reason we stopped using them; they became a serious embarrassment for Westminster; the IRA used the shootings for serious political leverage.
