She said "I did see Joel on several occasions outside of the mosque, actually, in the parking lot of the mosque,” the neighbor said. “It wasn't in the yard, it wasn't behind the fence, it was always in the parking lot when I would see him. And there was one time when I passed him, actually, on the sidewalk."
In the parking lot, is whole lot different than just "outside the mosque". IIRC the parking lot is inside the fence, but PKM can confirm that, since she did a "drive by" recon of it.
Parking lot is definitely inside the fenced area in the back and north side of the mosque.
I also did a drive-by (DFU posted the pics I took), and yes, the parking lot is behind the fence line. The parking lot is not closed off by the fence, mind you. But if you are in the parking lot of this place, you're on their property, and I can think of no good reason for being there unless you're visiting the Islamic Center.
