That's what Yasser Arafat's Al-Aqsa Martyrs Brigade discovered earlier this week. Apparently some intern in the Brigades' office was working hard, trying to make a good impression on his bosses. He thought, "I'll just try and get ahead on all these press releases I have to write taking credit for our suicide bombings."

Then, when the next suicide bomber blew himself up, he sent out the fax. The wrong one.

In its announcement taking responsibility for the terrorist attack at Ariel (27 October 2002), the Al-Aqsa Martyrs Brigade mistakenly indicated that its operative Muhammad Shakir had carried out the attack at Ariel. It turns out that Shakir was not the suicide bomber involved in the Ariel attack, but he was planning to commit a different suicide attack in Israel. The erroneous announcement exposed Shakir, and early this morning IDF forces arrested him in Nablus.

You can't get good help nowadays.
