Three Amigos plus one

The heroic actions of three Americans and a Brit, taking down a potential mass murderer on a high speed train in France was a welcome distraction from the cascade of bad news plaguing the world of late.   Quick thinking and disregard for their own safety enabled the young men to prevent a tragedy.  It makes us feel by association that we might also be capable of something similar if we were presented with the same alternatives.  It's a comforting, if somewhat unrealistic view in a Walter Mitty world.
