1. Michael's just happens to be in all these little plaza's. The name itself means nothing. It is the layout of the Plaza with the Greenspaces, adjoining parking lots and numerous vehicle exits that is the criteria.
2. The white van is a "tunnel vision" item. After performing some visual parking lot testing, I found that white vans are the "most" visible (unbelievably so), red cars were next, dark cars are almost indistinguishable as to color.
3. The Tarot card...I'm not even convinced that it was left by the sniper. The info on the .223 was out at the time and it's 9 shots into the scenario. Sounds like a nasty kid in the neighborhood being a smarta**. (But I don't know what the police know.)
From the few sites we know about...The sniper is on foot for part of this at least. He has a spotter BEHIND him.
When the shot is fired, he watches the sniper walk out. The spotter starts his car and goes to another parking lot for a pickup and drives into a residential area using the back roads and never getting on the main drags.
He has safe haven somewhere near Fredericksburg. Virginia is into the hunting season, yes? Guys in camoflage would not be an outstanding feature down there but would be up north??
Who knows! Just rambling thoughts.
