My concern with your post was not about your wanting an investigation, although your tone, posting about it in another thread and now creating a thread about it, makes it seem as if you are assuming they did something wrong...I didn't take you for a Red, comrade, but it seems you're trusting Russian intel more than our own. In the 50s that would have gotten you blacklisted.
No, I'm more amused at how you assume the FBI can just "keep an eye on" every Tim, Dzhokhar and Khal Drogo they get a tip on. Particularly, as I said, from a country WE don't like, about a people THEY don't like, about a people who don't have a history of problems with US.
Use your head, man.
