I hope you don't think these two are sane? I will grant you that greed and profit has been proven to be a part of their motivation to do this,but that doesn't mean it was the only reason.They could also have done it for thrills.
Muhammad had sympathy for the 9/11 hijackers and hated the US. He's an Islamic terrorist.
Only in the same sense as Gacey and Berkowitz were Catholic and Jewish terrorists. There are no reports yet that he was a member of Al Queida or any other radical Muslim group that is at war with the US. Until and unless proof of this is given,he is just murdering criminal scum.
