"I've also told them how people who do bad things to kids often make threats about how they'll hurt/kill people the kids care about if they tell anybody, and how they should tell me or their mother anyway, since as soon as we're told, we'll call the police and have the person arrested. (unless I get to the b*stard first, which is a bit of gruesomeness my daughters don't need to know about...)"
Now who's the crazy one? I understand that you want to protect your daughters, but taking the situation into your own hands before the police intervine is not a good idea.
...ok were you just joking, I really cant tell because the rest of this post is so serious
