Maybe flashbang grenades are too dangerous to throw around without warning?! There was a story I saw yesterday about police shooting a 95yr old WW2 veteran in his own home because he didn't want to leave and was brandishing a knife. They were bean bag rounds but they shot him 6 times from close range and he died.
