I’m not sure if that was really clever or just random.
I’m willing to take a bullet or a cut if it will achieve some purpose, but I would pull up short, at least for a few seconds, if I saw anything that looked like a bomb vest. It’s one thing to risk your own life, but a very different thing to risk blowing up an area full of people who haven’t had an opportunity to make their own decision known. Normally I try not to think too much when reacting to violence, but a bomb vest (or lookalike) would pretty much force me to stop and think.
