I think that’s not a reasonable argument, though. If you kill a cop, you will likely not survive it. You will likely not be arrested. If you manage to flee the scene, you will be hunted down with the cooperation of law enforcement from around the country. Right there in New Mexico, they just had a situation with a guy who answered his door with a gun and got blown away, cowboy style, by the cops who knocked on the wrong door. And it’s being considered a justified shooting. And the guys son happens to be a NM cop, iirc. People buy guns to protect themselves from other people who bought guns, not from the government.
