Justified, 100%.
And dear sweet gods... apparently there's a lot of people who forget that most of what comes out of Hollyweird is neither a documentary nor particularly educational.
As others have said:
1) Hollow-points aren't for maximum damage, they're actually BAD FOR YOUR GUN. Real gun owners only load them if they're concerned about the possibility of the bullet passing through the bad guy and continuing on into an innocent bystander. If you think the reason for loading hollow-points is greater damage, you're an idiot and need to remember that Hollywood is not in the business of education.
2) A laser-sight isn't a bad idea if you're concerned about accuracy. Considering this guy was licensed, is training to go into the military, and yet only managed 50% even though he was at arms' length, he needed all the help he could get in this case.
3) POLICE OFFICERS who spend regular days at the shooting range firing hundreds, if not thousands, of rounds into a target don't do anything other than shoot to kill. Center of mass even with rifles which are far more accurate than handguns. Even if he hit an arm or leg, a gunshot that hits the femoral or brachial arteries will kill you just as dead as a shot to the torso. You'll bleed to death long before the ambulance arrives.
4) He was attacked at night by MULTIPLE BAD GUYS. Only a moron, a suicide candidate, a seriously committed pacifist, or a Darwin Award contender would respond with less-than-deadly force and only an exceedingly bad and corrupt government would condemn a citizen for defending himself.
5) Pistol-whipping? Seriously? First, that only works in movies. In real life, severe blunt-force trauma to the HEAD is still life-threatening, if you're unconscious for more than about three minutes, iirc, you're probably not waking up. Also, even for it to work, you usually have to be behind an UNSUSPECTING VICTIM. Otherwise his arms are likely to get in the way and you're just as likely to aggravate the BAD GUY and risk him getting control of your gun and shooting you. Pistol-whipping is not used in SELF-DEFENSE, it's used by the BAD GUYS. And they're not afraid of hurting you, they're afraid of the noise of shooting you drawing attention and someone coming and trying to hurt THEM.
