I stand corrected.
I wasn't there. I imagine if I was, it would have been rather easier to spot. But honestly I have no idea why you are trying to defend what is obviously indefensible with this "perhaps they were in groups of no more than 6" nonsense? OBVIOUSLY they aren't all following the rules so whereas you've made reasonable points, your clinging on to this one just makes you look daft.
You don't even know the rules yourself mate, yet you have got on your high horse. You are accusing people of breaking rules and jumping to conclusions. You can't prove anyone has done anything wrong, so how can you fine or prosecute them?
I am not defending anyone. I have more to lose than most with Covid as it would kill me. I have no immune system and would be in big trouble if I got it. But I have tried to be realistic and think a common sense approach would be far better than the approach you are advocating.
Look at the picture you have posted, there are hundreds of people there. If the police rushed in and started giving out fines and arresting people, it would cause more trouble. The police would be better served walking round, keeping order and reminding people of their responsibilities. If anyone got out of hand, then respond. It's common sense, it's Pro active and the vast majority would welcome such tactics.
It is physically impossible to prove any of those people in the picture have broken any laws. You can come to your own conclusions, but guessing will not wash in a court of law. You can't prosecute someone or give them a fine, just because you think, you have to prove it. Say the police went round every person in that crowd and issued every single one, an in the spot fine. What if every person refused to pay it and decided they would fight it in court? They then go to court and say we are not paying it as we were in a group of 6, this is our group of 6 and we did nothing wrong. It can not be proven otherwise. So you fill up the courts pointlessly and it costs ridiculous amounts of money.
I am not defending anyone, I am being realistic. You initial rant was way over the top and your proposals would cause far more problems than they would solve.
