Being a police officer is a profession which naturally attracts people who are power hungry

These people are statistically more likely to use lethal force. A person being arrested by the police should NEVER die, and military grade weapons being readily available to officers makes that far more possible. I would never say completely disarm the police, they should have guns and they should have shotguns. But military grade assault weapons are something police don't need. If we are in need of such force, we should send the coast guard. Most other countries have systems like this in place and police violence is much lower per capita in those countries than the U.S.
