I used to be opposed to any sort of vigilante groups, until they found a prolific one at my daughters school last Christmas time.
He was insidious. He’d wormed his way in to a local children’s charity, was VERY involved with the school and often helped out at his wife’s brownie groups. He was chatty and friendly in the playground and had many friends.
He was talking to/getting pictures from 7 year old girls, daughters of his friends at school. Apparently some of the parents were quite irresponsible and their children were on bloody Instagram.
He sent topless pictures of them to other pedos and told them to go after them for more. He bragged that he’d had sex with an 11 year old...the exact age of his daughter.
And despite the fact that one mother had already raised concerns to the police he was not investigated.
We all only found out what a cretin he was when a local vigilante group got him to admit all of this and tricked him in to meeting them but pretending to be an 8 year old girl who would meet him when walking home from school.
If it had just been left up to the police he would still be preying around our school and on children.
