A pretty good example happened in Riverside a few years back, for what ever reason a woman was sitting slumped over in her car, the police approched the vehicle and something happened and the woman ended up shot dead. I personally don't know what led up to the the shooting but if they would have ignored her as a sleeping vagrant instead of investigating further to see if she needed help she may have died if she were injured but the police would have just had to take a report.
