But what better way to be able to keep up with little acts of terrorism than to not take credit for it and let people keep thinking that it was an accident?
Certainly not outside the realm of possibility. I just think not so likely in this case. Certainly our infrastructure (i.e. roads, rails, airways, utilities, etc.) are all prime targets, but even without the threat to terror they are all subject to accidents and failures. Without a concerted, coordinated campaign to foul them up, any would be terrorist organization loses visibility and effect altogether. As long as this is viewed as a freak accident, people will clear off the tracks and get back on the train the next day. If it is believed that there could be additional incidents in the coming days or weeks, ridership goes down, people alter their way of life and the terrorist achieve their little victory.
Just my opinion. I hand't heard anything about the jilted homosexual angle, and the other personal and medical problems this engineer had until I read this thread...those tidbits bolster my opinion this wasn't caused by an external party.
