I wouldn't be surprised if this is basically a distraction. They picked up a Jordanian associate of Mohammed Atta's in Hollywood, FL a couple of days ago. He was buying a one-way ticket to Palatka, FL, a town on the Amtrak line, and for some reason, they thought he was headed for DC after that.

I also think - although, of course, I'm always willing to accept reality if it turns out to be different from my scenario ;-) - that if these people get cornered at some point, they will then probably blow up their truck and themselves, trying to take as many law enforcement people with them as possible.

Maybe the shooter is just copycatting this episode of "HOMICIDE: Life in the Streets"
