Well a busy Saturday over, we have time to catch up on things.
First, the 100 dead terrorists number was taken from a book, cited above. It appears to be the only estimate I've found. It never occurred to me that people would really care how many terrorist were killed given that it was less than all. You got a better figure, go for it!
Second, people deflect responsibility for lots of reasons short of treason, and there are different types of responsibility short of intentional treason. Here they wanted to deflect responsibility because they were grossly incompetent, because their soft foot print theory was silly, and because they wanted to win an election. An investigation is ongoing.
