ROTFLMAO!!!! You are correct in most circumstances
poor 72 yr old whose door the cops went to late at night answered the door in his underwear when they banged like hell on the door...was NO threat and they tazed him and messed him up bad...when he fell....was in the hospital for months
True but that negates the choice of non lethal force. This can be corrected by better training, especially when confronted with real world criminals or life and death situations. I see your point however.
