No one knows whether they're right or not after submitting their ideas to the crowd for a full and proper vetting, either. 'The crowd' is not a substitute for experimentation and investigation. Noticing that someone looks suspicious in a picture and reporting it to the proper authorities (preferably a division thereof known for evenhandedness) so that they can look at all sides of the issue is reasonable. Someone has to handle crimes, and whoever that someone is will always be human. Noticing that someone looks suspicious and posting their picture on Facebook with an accusatory tagline is entirely indefensible. It's bad enough when their are no proper authorities.
