No, absolutely nothing deserves a fatal kick to the head. Nothing can call for the way the gourds were acting, as they should have the training and mentality to handle things without violence or only subdue people if necessary until police arrives. I have never contested that. So, now you can stop with the verbal assault, by calling my out to be an absolute idiot.
But, yes, I knew, but not defending the outcome, that the Brits did not accept the way and culture, as they started to point and one actually wanted to fight with the guards. They walked around showing anger in public and where screaming. Basically doing everything to escalate the problem. They should have asked the bar to call the cops or continued to keep the argument and discussion on a decent level.
