Remember, Mohammed Atta was just a "typical moderate Muslim" to all appearances until he got on the jet.
How many other Islamic time bombs are ticking among us?
This is not at all an insignigicant question!
According to Richard Pipes, 5-10% of American-based Muslims could be in that category. That's a lot of people, not to mention a big sea for the fish to swim in.
But that figure does not count our indigeonous Farrahkahners, Islamic-born-again convicts, unknown Islamic border-crashers, organized street gang opportunity-seekers, university sympathizers, Liberals and other assorted hard-leftists, fascists and orphaned Communists.
All in all, a lot of potential killers are roaming around unfettered out there in The Homeland just waiting for the opportunity to go public!
