Seriously? In a democracy?

You organise an event, inform the Police of your gathering and then turn up and protest.

You don't break into events where you aren't invited and disrupt them.

'Who are you and how did you get in here? I'm a locksmith. And, I'm a locksmith.' (Leslie Nielsen)

Never mind them, with the expressions from those in the audience milkshakes are the least of our problems.

But this wasn’t aggravated trespass.

Of course it was. I have already posted the definition of aggravated trespass:-

You must be doing two things to commit aggravated trespass:
1.Trespassing
2.Intentionally obstructing, disrupting, or intimidating others from carrying out ‘lawful activities’.

What these idiots were doing fell into both categories and I would like to see them all prosecuted

Not so. They were not found guilty of anything. No Magistrate ever would have done so. You are confusing British precedential law with Napoleonic law.

Sigh

Anyone that doesn't agree with you automatically is bonkers, you have always made that clear. And as someone that believes in cerebral hygiene there is zero chance anyone can convince you to agree with them.

As a Judge I would have thought you of all people can see that the protest was not viewed as illegal and therefore presumably the threshold for being aggravated trespass had not been crossed. There is plenty of precedent on this issue, both in UK law and also from the UCHR.
