If only people behaved themselves in airports and didn't do things like smash policewomen's noses.
Sometimes something like that happens and blokes lose it, some kind of animal instinct takes over. I always remember how a bloke horribly insulted my wife in a nightclub many years ago and I lost it, cringe when I think of it now of course......But obviously the cop shouldn't have done what he did, it's Britain not Russia.
I bet he deeply regrets it now, as we've all done things in the heat of the moment that we regret. (I'm not excusing him, he has to be punished)
I hope riots don't ensue. This would cause deeper hatred in the UK and give certain minority groups an excuse to escalate divisions.
