Yes there is. They found 6 or 7 of them in an apartment complex behind the Laurel mall on Rte 1 in PG county. Apparently there lived there a well connected Egyptian who flew the coup after 9-11. I see a few of them around here now and then. This is definitely one of their magnet places, along with Trenton, NJ, I believe..
Considering the recient court case there -- go figure! Birds of a feather flock together.
I have been worrying ever since the LA riots that the Nation of Islam would hook up with a Middle Eastern fundamentalist group. It appears to be happening. Therefore I am inclined to believe that the current shootings could just as easily have been a native, well-trained Nation of Islam member as a Middle Eastern immigrant (though I lean away from the Nation of Islam theory). The gangs would make particularly good recruiting pools for Al Qaeda.
