""The FBI has said its investigation didn't find any links between Hinrichs and terrorist organizations. Agents have said they may never know whether the student wanted to get inside the stadium.""

"Terrorist organizations". How about LE telling us what organizations he belonged to, and we can decide on their description.

He was seen visiting the local Muslim Association/Mosque--same one Mossouie (well, I'm sure it's spelled wrong, but the so-called 20th hijacker) attended.
