Did anyone watch? It was pretty interesting. It seems that although the FBI watched these guys for while and knew that they had lied about being at OBL camp in Afghanistan - there is very little/no evidence that they actually were a terrorist cell. That once the White House was notified about the large Arab populkation in Lackawanna, the Pres. and co. took a personal interest to arrest someone.
That the ringleader (who was not arrested) was killed by the US in that car attack in Yemen and he probably was a threat but since the US killed him no one will ever really know.
The amazing part is that these guys will probably be out in less then 10 years - which lead one person to ask is if they were a truly terrorists why would the US allow such a lenient sentence? The White House had these guys declared enemy combatants (under the Patriot Act) to avoid having to disclose any info.
There is an article in the NYTimes about it as well.
