I should be sleeping, but the "4th-floor shooter" shit is bugging me.
Here's roughly where the strobe was. This is a terrible place to put a shooter. An absolutely horrid angle on the target.
Now here is roughly where the shooter was. Appropriate elevated position for the best view of the entire target area.
So if I'm some "entity" that's planned out all the logistics of this attack, why put one of my assets in a bad position? A more appropriate place would be here, in the south tower of the Tropicana...
Makes the most sense. You have now set up a crossfire, have a chokepoint at the entrance/exit, and have introduced even more confusion.
I'm probably out of line with this post, but it's bugging me that people think there's another shooter in a terrible spot when this seems to have had a lot of planning.
