My point is that flak jackets don't kill people, and automatic weapons don't unless they go off. Stun grenades might if they cause a heart attack, but so could the pressure of a police investigation. So could a speeding police car. You presented the issue as 1-5 people a year being killed. If you agree it isn't significant then what is the problem? Because it isn't that it causes deaths. If you're going to tackle perceived problems with American policing there seem to be far better areas to address than "I don't like paramilitary raids that don't actually have statistically meaningful adverse outcomes".
