We have a small group in our society who are a malignant and dangerous cancer. Unfortunately, the police have a problem cutting them out in a crowd.
It isn’t just the thugs that were the problem. It was the spectators and looky-loos who were breaking the law after it was declared an illegal gathering and ignoring the warning to leave peacefully.
In their actions of staying and wanting to share the adrenalin moment; their social media pictures and tweets, they are just as responsible as the thugs.
