Depends on what and who he gives up, he is looking at 15-20 years minimum in the SuperMax.
While the media is saying the targets were in New York City, remember there is the "Islamic March on Washington" next Friday morning..
The event in Washington with 50,000 people is the perfect opportunity to slip some London-style backpack bombs around in the crowd, and get right up to the steps of the US Capitol.
Perhaps this guy in Denver is just a "plant" and/or diversion and the real attack is coming in the crowd participating in the march on Friday?
They are saying 50,000 people... on a work day. Because of traffic etc in DC on a workday, security wouldn't be really tight until close to the Capitol and House and Senate Office Buildings.
The Capitol Police wouldn't want to "offend" the visitors you know, so I don't think they would be searching people on the Mall.
Plus the DC Metro Security would have a difficult time with usual work day commuters on the subway plus the "Muslim visitors" riding as well. Try searching EVERY backpack.
I just have a bad feeling about this. Plus if something happens, in the course of an Islamic event...a tragedy might encourage some segments of the US population to "take it out" on otherwise innocent Muslims, causing a PR nightmare.
