Having watched the video, the main issue I take with it is the people outside standing behind that thin wooden enclosure.
If anyone is in any doubt about the sheer penetration power of these weapons,
this page should make it abundantly clear...
The other thing I think could have been made very clear is this. They show the police treating people as if they are a threat. But they do not make the key point. Even if the police are shouting at you and pointing a loaded weapon at you, even if you can't see their face or their eyes but can only hear them shouting at you, you are
SAFE.
Doing anything but doing what you are told and calmly carrying out all orders will make you
UNSAFE.
I know it's enough to unnerve anyone when a paramilitary officer points a weapon at you and shouts at you. But the simple point is this, if it were terrorist you would already be dead. So be calm and do as you are told. It's not something you can imagine when you have not experienced it but looking down that barrel is somewhat unnerving. Trained military do not deliberately point weapons at peoples faces, whether unloaded or carrying a blank firing adaptor.
One other point. Assault weapons do not sound like starting pistols unless they are very far away. I've worked in the Butts of people firing at 300m away. The sound you hear is crack, boom. The round is supersonic so the first sound you hear is the round going through the target (the crack), the second sound is the boom of it firing from 300m away.
If anyone is in any doubt about what it sounds like, close up, watch
this. Even then this does not do justice to the actual sound. The one time I forgot to put my ear defender in when firing a relatively small 9mm round, my right ear rang for several minutes and the sound was actually like a blow.
If anyone is really interested in the technicalities, just watch the barrel of that gun when fired. In single shot mode you can see it kick up and right and he has to adjust it every time. In 3 round burst you can see that it kicks well up to the right and has to be brought back down again. In full auto it's all over the place. Just think that a small, 1/4 inch difference of the barrel at 30m can be right off target.
I know it's boring and overkill for most people but these are actually the things which enable people to survive in wars when they are tasked with attacking this kind of fire and winning the position.
