I think I got the gist of the video... looks like multiple robberies in progress, done by a large group of people/youths, *armed* (but can't make out with what they are armed with).
Brings to mind something I tell my friends and family. After a night out on the town if you're boozing and all, there are things to consider. Designated Driver is the usual one, so everyone gets home safely, which is a good thing. But that simply shows that those that are drinking *know* they are in no position to drive.
Now how about defending yourself effectively? your reaction time is slower, your vision, your state of mind... all are now compromised. Just something to think about.
If you're going to get robbed you;re going to get robbed. You can choose a safe route to your home/car/etc but if the badguy finds you they find you. Multiple badguys, weapons, the usual suspects. Not an easy situation to get out of if things go from bad to worse, especially if you're also drugged/liquored up.
