He's baaaaaaaaaaaaaaack!This has nothing to do with who is a victim. Cops get specifically called to situations with known criminals. CCW holders do not get called to dangerous situations.
You would have to make the comparison as to how many cops get attacked just being in public (walking into a store, etc...) not on a call, compared to CCW citizens. That's probably impossible to do.
Cops draw their weapons a zillion more times than CCWs and thus the likelihood of a shooting is going to go up.
