I'm not suggesting police should never carry guns! If you're going to apprehend a suspected murderer, you should probably have a weapon on you. But if you're going to e.g. help a heart attack victim, I think it's reasonable to ask officers to leave their guns in their car, just as a doctor wouldn't bring a gun. I'd expect exceedingly few officers to be killed as a result.
