I know that I would be one to act with my weapon. This comes down to preparation mentally as well as physically. If you do not prepare for the use of your weapon then you should not own it, it WILL be more dangerous in your hands.
Even if you did not kill this person, a shot to them would make them realize that there is an immediate danger to his life, which I am sure he knew was not there.
Also, as has been stated, gun control is BS. Those here with PERMITS have done it legally and how many have they killed/shot for the heck of it?
Those that get them illegally have most likely done far more damage than those who legally carry.
My home and person is protected at all times with a weapon and I will not hesitate to use it for my protection or protection of others.
The other thing is the media. They give the bad guy the attention instead of the victim. They can get their 5 minutes of fame and this leads to their desire to do it. Just like car chases, stop broadcasting them and they will diminish.
The political correctness is to blame as well. No one is held responsible for their actions. This action should result in his death, he admitted to doing this.
Society has too many excuses to use because it is tolerated by society.
