Fail.....So you're afraid that someone's trying to break in to your house, so you grab your gun and immediately.....go back to watching TV?
Retreating to the bedroom.....good. Grabbing the gun.....good. Now STAY there, grab a phone with the other hand, dial 911, and hope that your tax dollars go to work and save you the trouble. Pray for police but prepare for war.
Fail....HD weapon missing a weapon light. Being able to shoot your attacker is good. Being able to blind your attacker with a 300 lumen light so he can't shoot you while you're shooting him is better.
Biggest Fail of all.....hesitating to shoot when you had both opportunity and reason. If you're going to pull it out be damn sure you are both willing and able to use it because in reality the bad guy won't faint. Even if they surrender, holding someone at gunpoint is INCREDIBLY dangerous, even for trained law enforcement. Commit yourself to ending the threat to your life and don't take any changes.
