The military-aged men in the background appear to be disciplined and able to follow instructions, whoever is giving the instructions.
I have a real concern there may be thousands of military-aged males in the U.S. that are ready to do what they are told and that are capable of sweeping a lot of silly girls along with them.
I can't really prove my concerns are justified just from looking at video.
“Thousands...”? I’d say it is millions. Go to the range...stay/get physically fit...buy ammo.
