TERROR ON A TRAIN. InstaPundit has a link to a report of a plastic-knife-wielding man who had a bit much to drink and threatened some passengers on Amtrak's westbound Sunset Limited, somewhere west of Jacksonville. (InstaPundit puts the train at Big Sandy, Texas, unlikely given that the arrest happened around 8 pm on a Sunday evening, with the Jacksonville, Florida paper picking up the story.) Weblog commentary draws parallels between the United Flight 93 passengers and the passenger reaction on the train. Perhaps. But those cross-country trains draw a pretty no-nonsense crowd. Somebody who got liquored up and disruptive likely would have been subdued by other passengers before September 11.
