I'm being hated for ruining an "innocent young boys life"

Two weeks ago my neighbor was knocking on me door and when I answered he was holding up a young "boy" by his shirt. This boy is 18 btw. He told me he was recording my daughter outside her window while she was changing. My daughter is 11. I took his camera and he was infact recording my daughter and had videos of her changing from different days and other young girls too. I called the cops and blasted the situation in the grapevine group on Facebook to let people know to get their daughters curtains because this creep is recording them. He is facing being put on the sex offender list and also facing some child pornography charges. I have started having people tell me that's too much for an 18 year old and he's just a kid. Don't ruin his life. He was just being a "boy". I teach high school. I know plenty of boys who don't act like that. That isn't being a boy and not that it would make it better but my daughter wasn't another teacher. She doesn't even have breast yet. He's getting off to a little girl! Most of the mom have thanked me for alerting them but I have people hating on me for ruining this young boys life. Would you guys have not had him arrested and warned other mothers about him. Especially while he's out and about on bail. He will probably get a slap on the wrist for what he's done
