Well as I said I think it was an inside job. Mrs Zing thinks the militant Islamics did it, but she thinks the US knew they were going to and did not act, so in essence she thinks it was an inside job since they did not stop it.
I don't need a poll to tell me what the Physics says
I suppose the racist story about how 19 Muslims did it could theoretically be true, but why are two dead hijackers still alive and flying for Saudi Airlines and why has Osmar Binladen still not been indited through lack of actual evidence?
