What should've been done.
So the girl was annoying. Have you all forgotten how annoying the girl was was in "The Blair Witch Project?" Anyway, the annoying girl wasn't the problem with the movie. Problem was that they are a bunch of idiots because when they broke into the guy's house and saw all of those guns, I would've taken the shotgun and pistol, and held the child predator at gunpoint until the cops arrived. Or I would've killed the sicko if I had to. But they leave the guns where they are, and later are killed. Idiots.
Another thing, Being that the police were taking their sweet time, I would've done something in the neighborhood for the neighbors to call the police on me. That way, the police would've got their faster, and I wouldn't have to go into the house.
