I see a problem with someone thinking you'd have to search criminal records of all users when this is about KNOWN dangerous persons. The example given of a pedophile that is known, would be based on public info, or perhaps previous flagged posts, etc. I see that problem someone isn't thinking much about the OP and just grasping straws in order to complain while not offering any real substance to the issue/task/question at hand. No go troll elsewhere. Thanks.
