WayneH, you are right, I don´t get it. If law says, it is ok to shoot and kill offenders, why do offenders win lawsuits? Please note, I am not agreeing on general principle on those lawsuits.
It is the duty of the executive to get the facts. IF the use of force was overdone by the defender, then, yes, the defender is breaking law, too and would be viable for private lawsuit with high chance of winning. Such a lawsuit is not frivolous.
Well, I donßt think the person suin for the hot coffee, did buy the coffee to put it on the legs. It most certainly was an accident that it got on the legs. But giving out coffee with a temperature of about 96 degree Celsius (with water boiling point under normal atm at 100 degree Celsius) isn´t really responsible either. Imagine, that you hodl teh cup in hand, spill it on your hands because of too many peopel there and one stumbling in you. That gives pretty burn wounds...
