To put it simply, this article is about law enforcement using the internet to catch crimes. I think it is an invasion of privacy but it does help cut down some crimes before they happen. The problem with that though is that everything on the internet is exaggerated out of proportion. Some people could say that that they are going to blow up a building, but they could just be joking the entire time. As long as my information isn't published on the new or something then I don't mind the fact that my privacy is being thrown out the window, I'd rather have a false sense of security than be in danger of some high school shooting or something.
