Yes they did they shouted ALLAH many times before they crashed the planes, you know Tim Mc Veigh bombed the building in Oaklahoma for government policies only.Which plane were you on where they did that?
It was nothing religious.
Elohim City's version of Christianity was built entirely on hatred of the government.
McVeigh's act was very likely religious.
SO what was he doing in the name of religion? WACO was a cult nothing more there are plenty active cults out there.
