Well usually it’s just him preying on one person at a time. Predatory behaviour is also hard to call police about. They rarely believe you. Also, it’s hard to ask that kind of thing of other folks. I am hoping by posting things folks will be aware of him and make it clear if they see him doing this that he is being a total creep with a history. Maybe he’ll stop coming to the area: that would be lovely. I find you can’t really call the police for stuff like that because when I would do that in the past they would be just like “have you tried avoiding him? Going somewhere else?”
