But your odds of being shot by police in a given encounter drop to zero if the police are not present.
Yes, and my odds of dying in a car accident are zero if I never get in a car. So? Sometimes it's necessary to call the police. Not doing so because you're afraid of being shot, when the odds are probably a million to one, is stupid. The logic of avoiding a tiny risk only makes sense if there is never any utility in calling the police.
12 years ago my wife's nephew, who was 10 at the time, was visiting from out of state with his parents. While in our living room, he choked on a pretzel. We called 911, who dispatched a cop, who arrived in 2 minutes (we have very fast response times in our town). We were trying to Heimlich him but it wouldn't come up and he was turning blue. The cop took over and the boy immediately expelled the pretzel. It's possible it would have come up anyway without the cop, but it's also possible the cop saved his life.
Should we have not called the cops then because of a remote chance the cop might have shot us?
