NOW I get it

I couldn't understand what was going on at the Moussaous death penalty trial. But now I do.
First, you need to know that there are still some lawsuits going on between the airlines and the families of the 911 victims killed in the plane crashes.
So I guess the airlines were worried that the Moussaoui trial testimony would affect these lawsuits.
So the airline lawyers allegedly got some help from the Transportation Security Administration lawyer to try to make sure the airplane people testifying at the Moussaoui trial didn't say anything which would jeopardize the airline defense in these lawsuits -- for example, to criticize airline security screenings.
The almighty buck rules!
