The New York Police Department, which is working very hard to spot the next terrorist attack, is talking about some Muslims who are engaging in pseudo-assimilation to try and blend in, but actually more radical than ever.

NYPD warns of homegrown terror threat - Yahoo! News

NEW YORK - They preferred bookstores or hookah bars to mosques. They stopped listening to pop music and instead surfed Web sites promoting radical Islam. They threw away their baseball caps and grew beards.

New York Police Department intelligence analysts have concluded those were some of the telltale signs of homegrown terrorists in the making – a mounting threat as grave as that from established terrorist groups like al-Qaida.

An NYPD report released Wednesday warns of a "radicalization" process in which young men – otherwise unremarkable legal immigrants from the Middle East – grow disillusioned with life in America and adopt a philosophy that puts them on the path to jihad.

But if someone is an immigrant, he can't be a homegrown terrorist like Bernadine Dohrn and Bill Ayers, or even like American Muslims John Walker Lindh and John Allan Muhammad. They're immigrant terrorists, part of the modern phenomenon of mass immigration which brings the problems of foreign lands to America.
