I was banned from this thread because I apparently mentioned America, so apologies for my absence. I'm not sure if this was posted already therefore but looking back a couple of pages I couldn't see it. This was in Birmingham yesterday. Spoilered because it's horrifying.
The sheer casualness of the assailants to what they're doing is jaw-dropping. They absolutely regard the dude pushing his kid along as an entirely separate individual to their group.
The police have actually arrested them in this case, but when you see videos like this going around you know it's not over.
