Read it can come to your own conclusions - but to me this is rather simple. You can break this into the Most Likely and Most Dangerous Courses of Action (COA).
- Most Likely COA: They were intentionally trying to start an incident in order to get PR, raise Cain, perhaps a lawsuit, and generally vex the Infidel.
- Most Dangerous COA: This was a very poorly executed Dry Run to see if they could get away with a planned action before they actually did it.
UPDATE: Via Jawa, Dennis Miller puts a nice spin on the whole thing.
