Could this be John Mohammad's way of getting back at the government for the life without parole sentencing of Jamil Abdullah Al-Amin, found guilty on March 9 and sentenced on March 13th?
Is Jamil Abdullah Al-Amin the one that they were chanting to free at the reparations rally in September in D.C.?
H Rap Brown could be one of the factors that motivated Mohammud.
I don't think that there was just a single factor. I believe that he was more in sync with the original bombers of the WTC and then off course those responsible for 9/11/2001. He would have sympathy for H Rap Brown, but I doubt if Brown was a really big motivator for him.
