Speaking of testicles, I saw a video last night of a man on a motorbike ride alongside just before the event began in earnest and jump from his still moving motorbike on to the side of the truck at the drivers door.
That takes some huge balls! I don't think he had much chance to change the outcome but he tried.

Now, if he had been that heroic with a Glock 17 in hand, this event would have been over shortly after it started.
Maybe the French will see that their citizens are not afraid, just unprepared and stripped of their rights to self-protection.
