It's very difficult to get followup of a LOT of stories, whether they're Muslim-related or not.
When I was trying to actually find out the real story of what happened to the "Three Arab terrorists locked themselves in an airline bathroom and were shaving themselves in Arkansas" story afterwards, I had to do a lot of research and look at local news sites to discover it actually was an Indian gas station owner on his way to a Las Vegas convention who decided to shave his face during the flight and stayed in the bathroom a long time, his friend (who was never in the bathroom) and a random Hispanic guy who was sitting near them who had nothing to do with them (and never did anything and never went into the bathroom) who looked like an Arab.
