First there was Adam Yahiye Gadahn (nee Perlman) now there is Ahmadulla Sais Niazi. Both lived in Tustin, just at the northwest of Irvine.
But hey. Irvine had that egyptian couple that kept a slave in their garage. And an arabic guy who shot up the LAX El-Al booth soon after 911.
This year, its only February, two murders so far.
