Whether or not to allow armed, suicidal terrorists near a plane of civilians is a tough call
Yes, it would be good to catch them in the act, but then what if they succeed in killing a lot of people along the way?
I don't really second guess the French on this one...yet.
They have much tighter doemstic intel than we do, and they may have enough pieces put together to run the sob's down and still catch them and wring some good intel from them.
But then again, it is the French.....
