Nah, they should have looked at the complaint and realized that it wasn't an actual threat and that should have been the end of it. They shouldn't have charged the guy who complained with making a false complaint, but they should have told him there wasn't enough in those posts to do anything about. I don't doubt that guy was fucking with the company that owned him money, I doubt that he was actually threatening to shoot anyone. Police should absolutely not be knocking on people's door to tell them to stop being cunty on the internet. That's not their job (or at least it shouldn't be).
