but Google knew what I meant with just one letter:
Looking at a story from NYC media, dude is obviously a gangster. Short hair, flat expression, long criminal record.
The "news" accounts emphasize that he's not political or "terrorist" but miss the more obvious criminal motive. Halting a train or coach is a time-honored way to rob lots of people at once. Either he's practicing for a bigger operation, or the other gang members were ready but decided not to proceed.
