I can only imagine how WIDE this effort is.....
Looks pretty darned widespread. I found one here in PA called the "MASJID MUJAHIDEEN". It's in Philly, and it has been listed since 2000 as a "church."
I would very much hope the authorities AND the locals are at least SUSPICIOUS about any church with "warriors" as part of it's name, especially after 9-11, and MOST especially because the perp(s) who planted the nail bomb in a mailbox have not yet been caught.
