Our valiant egyptian police

Our Egyptian police is so on the case of the Sharm Bombings: They arrested the mastermind behind it. How do we know? They announced it! Now, color me confused, but didn't they already find the mastermind behind it and killed him and his wife? Oh, that was another mastermind? Ok then! Heh, got to give them credit though: they didn't kill that one. Hopefully he won't go crazy in jail and bang his head to the wall to death like that other dude did. Sigh...
