I doubt that old man could run back and forth to those two windows several times in 5 minutes without being winded and exhausted, or having a heart attack. Let alone do it while reloading them all and firing them downwards out a window. The other videos showing shooting from other areas prove this is not a lone wolf. Its more contrived propaganda so you will patriotically hand in your weapons for the good of society. Then no one can resist beyond screaming bloody murder as your educated on how the world really works.

there are no windows blown out. some have mentioned they may be visual smoke alarms triggered on the 4th floor. Unless the windows are blown out, this is a nothing burger.. Are the windows blown out? This shooting is 100% false flag, but this particular lead may be a red herring.
