Hello!
The building is nearly covered with MIRROR GLASS!
One can see a group of large signs reflected just next to these claimed 'muzzle flashes'.
What is blinking off in the distance that has reflected from the windows that have some assuming to be other gun fire?
I still can’t understand the psychology of the conservatives that defend the second amendment to the death, but when a possibility of threats to that very amendment from inside gov’t arise, they are blithely dismissed.
