Get a dog to bite one of them

There is this nasty growling aggressive stray that has been foraging the area. You see it making its rounds each morning when you get the paper. A couple of times it confronted you in your yard growling and acting mean and aggressive. You start feeding it, slowly taming it. You now have a nasty looking dog. But no one knows its yours. You train it to attack and one fine day you yell "Sick em!", When one of those young people are leaving the house. The dog rips that kid three new assholes. Blood everywhere cops called. The young Man lives but he needs lots of stitches. The dog is shot by the cops. They enter the house when they find the meth the kids was transporting all over the yard. Seven criminals are arrested and led out in cuffs. A haz mat team comes in for clean up. Victory!
