No gun law or gun restriction measure would have or could have prevented what occurred. A person could have done the same amount of damage with a 9mm handgun, loaded with self-defense ammo and a few clips in his pocket. You can scream AR-15s are the devil, take away all guns, blah, blah, blah... but the bottom line is that too many guns already exist in our country, many of which are not even registered, and it is impossible to get them all back. If they are out there, evil people will find them and will use them. i want mine to protect my family.
