1,000 people killed doesn't strike you as an unusually high, regardless of circumstances?
Not inherently, no. There are over 1.2 million police officers in the US. If the deaths are evenly distributed, for every one cop who has killed someone, there are over 1,200 who haven't.
In 2010, there were over 13 million arrests in the US; 1,000 deaths implies less than 0.008% of police interactions (not including traffic violations) end in deaths. That doesn't seem outlandish for a very dangerous line of work. But as I said, we really need more years of data to draw meaningful conclusions about whether this is unusually high or not.
