It is always tragic but you have to keep it in perspective. Last year there were 250000 misdemeanor arrests in NYC and only one resulted in a fatality which was the Eric garner cigarette case. We have over 300 million people in the US and God knows how many cops. More civilians kill cops than visa vie. Again, the numbers are tragic anyway you look at it but when taking in account the size of our population it is relatively low. I do own a gun the only thing I ever use it for is target shooting.
