Israel has been doing that for years. Suppressed Ruger 10-22’s to the leg, I’d prefer the kneecaps. Originally used to take out the dogs when making a raid.
They’ve had issues with that as well. They have reduced the number of cases where that is a viable response as it still leaves, say, a suicide bomber able to pull the detonation cord or press the button.
My dad, who was shot in the left knee in WW2 and Korea, always said that after enduring all the pain and eventually losing his left leg because of those wounds, that is where he shhot some one if it came too that.
