Mr. Heft appears to be, for lack of a better term, one of the good guys. He tried to counsel some of the accused, including the hysterical leader, and steer them away from extremism, at least on Canadian soil.
According to the CBC interview transcript, the leader once talked to him about the “martyrdom operation of Sept. 11,” so Mr. Heft said, “I was telling him that it hasn't even been proven that Sept. 11 was actually done by 19 hijackers. That was just the alleged story of the U.S. government. All I tried to explain to him is that whoever did it was wrong … And then I started to just talk to him about how we haven't even proven that the people who had actually did it were Muslims.”
Yes, that's the main difference between a bad Muslim and a good one: the bad fellow praises the 9/11 attacks, the "better" one thinks that Muslims didn't even carry out the evil deed.
