The whole point about having a pistol, is that you don't have to talk so much. That's the charm of every Clint Eastwood character going back to his spaghetti western days: Your gun does the talking. This guy was speechifying like some kind of filibustering senator. Plus, Clint Eastwood's characters are efficient... they know how many rounds they have fired, and they don't waste extra rounds just to feel good... extra rounds just shows a lack of self-control.
Actually, this douchebag had a great opportunity to give his daughter a real lesson in life that might help her over the next 10 or so years: Just because you think it's hidden and private on a computer, doesn't mean it's hidden and private. If he wasn't such a child himself, he would have chalked up her Facebook post as a 15-year-old girl being a 15-year-old girl in modern America. He should have then sat down with her, and told her that over the next 5 to 20 years, a whole variety of dudes are going to try to take photos and videos of her, and she is going to think she loves some of those guys, and some of those guys are going to love her back, but relationships end, and guys love to brag, so don't get drunk and have some boyfriend take photos or video of you with his member in your mouth... because it's gonna end up on the Interweb, and as embarassed as you are that I saw your private spleen-venting on Facebook, you're gonna be way more embarrassed when your kids, and my grandchildren, see photos of mom with some strangers wang in your mouth.
