Curiously interesting. The sniper does seem to be more than a run-of-the-mill-disgruntled-kid-or-former-employee. He seems to plan each assassination.
I never thought the calender portrayed 9/11, but instead, the egyptair crash. I always took it to mean that those with inside info acknowledged it as an islamikazi act, and mot the CIA testing surplus stingers in the harbor.
In that light, the PA cartoon is even more damning, IMO.
