Some try to help. There was off duty NYS Highway Patrolman trying to stop armed robbery at a supermarket. He got shot to death with a .410 by another armed wacko. Someone mentioned Germany (I think the shooting happened in Scotland), I looked at figures from different countries adjusting for population differences and looking at number of serious gun incidients. It boils down to large number and easy availability of firearms. That's the difference, if you choose to have an open mind and adjust for variables.
