@36: You insist that there are no ("Zero") cases of people being wrongfully killed by police officers. And then you concede that an example does exist proving you wrong, but because you're asking the question of someone else, you're entitled to just ignore the evidence I've provided you.
But here, let's put this one to bed. Over the 2003-2009 interval, there were about 400 arrest-related deaths per year attributable to homicide by law enforcement. And of those police killings, a full 25% were of people who were not accused of any violent crime (including simple assault). That's 100 people every year who are killed by police officers even though they weren't engaged in any sort of violent conduct. (source
