My guarantee that if everyone were equally weaponless - and led by example - everyone would treat each other with respect.

The effectiveness of police has more to do with the perception of lawfulness and fairness, than the power of the weapon.
Like I will deposit all my trust on an agency with a legal monopoly to violence. When the system fails, I am my own failover. When the system fails, the cops become the crooks.
