The idea this man was groomed is just totally weird to me. I would have said the same a year ago. But near me there has recently been a case that changed my mind entirely.
A young man with LD, socially inept, was contacted by a Hunter group. He went on to try and meet what he thought was a 13 year old girl in a secluded, covered area, and they cornered him, filmed him cowering, crying.
Longer version: He had been posting in a few chat rooms, was trying to find a girlfriend. They kept initiating conversations with him. They showed a lot of interest in him, their messages, the few that the police saw fit to discuss, flattered him, kept offering him friendship and a day out in the local town. Eventually, having explained his trouble with open spaces, the group identifed a space he felt comfortable meeting 'the girl' in.
The young man was not arrested, let alone prosecuted. The group was warned off, told they had acted in a manner that would get them arrested fr harrassing vulnerable people. Their response was to plaster pictures of him and their version of the story all over Facebook. It was taken down and the author arrested - convicted too.
But locally? The tale of the local pedophile that got away with it persists.
So now, any qualms I had about these Hunter groups have been magnified and I cannot believe any good will ever come of them. From both sides: allowing real pedophiles to get away because of their actions to groomng the vulnerable in order to fulfil their thrill seeking. They are dangerous and should be stopped.
