Where ‘see something, say something’ dies here is the nature of the online postings. They’re for people who have similar twisted concepts about life and morality. They’re not going to the police. If anything, they hate the police. Even if someone reported seeing one of his posts, I doubt the police could do anything. Countless posts that could be considered threatening are posted every day.
