We got stab vests years ago, and I don't think that it was from any one specific incident. Number of people saved by stab vests in the past few years number two as far as I know. One fell off his motorcycle while wearing his and the other was accidentally stabbed by a doctor with a needle at hospital after he walked out from behind a curtain with the used needle in his hand. Those are the two that I've heard of - they may of course be more. I tend to use mine more as a body warmer on cold nights, it'd only slow my running away. But they should be issued, to give crews the option to wear them. You *can* get covert ones to wear under your shirt which may be helpful. Good luck billing your service for that though.
