He's actually very well informed.
Sharif and Said Kouashi, the two brothers for whom the French police are searching, were born in Paris of Algerian parents, Mokhtar et Freiha Méguireche, according to a profile published by Le Monde. Said was born in 1980. Sharif was born in 1982. The brothers were poor and unemployed. Sharif did not finish school. The Kouashi brothers sometimes delivered pizza to make a little money. They were involved in petty crime as teenagers.

One member of the congregation at the al-Da`wa Mosque was Farid Benyettou. He was only a year older than Sharif, but was learned in Muslim texts, and taught informal classes at his apartment after prayers at the mosque. The boys began spending time with Benyettou. They stopped smoking, stopped getting high. At his apartment, Benyettou took them on the internet, and showed them images from Bushs invasion and occupation of Iraq. Sharif said, It was everything I saw on the television, the torture at Abu Ghraib prison, all that, which motivated me.
Benyettou ran a recruitment ring targeting young French Muslims that sent them to fight US troops in Iraq. They jogged in a park to get in shape and got rudimentary training in how to handle a Kalashnikov semi-automatic. They would tell their families that they were going to study in Syria. And they would spend some time in hard line Salafi schools. But then they would slip across the border into Iraq.
Sharif was about to go to Iraq in 2005, himself, to fight Bushs troops there (which he saw as aggressive foreign occupiers), but he and a friend were arrested and interrogated by the French police.
