That would only make sense if there was no other way to prevent these crimes. It's like asking for "numbers" to justify not putting every 16-25 year old male in prison. It would drastically reduce the crime rate! The numbers are: innocent people and police are dying needlessly, and any potential effect on the crime rate could also be achieved without those people dying through better policing strategies. It's pure waste.
