|Just following orders...|
Following orders regardless of legality, like mindless zombies.
Don't be alarmed though, they're from the government and here to help. The question is, to help who?
Curtis has a nice collection of 'domestic military exercises' here in CONUS.
Watch them all here.
Seeing as they're training with blanks, how would they react to receiving actual fire from someone or some group on Overwatch? What a clusterf*ck that would be!
I'm not advocating it, just asking you to think about it.
Next time, they may not be using blanks.
