The problem is you have to fight for these things every generation.
It's a mistake to take things like trial by jury, open justice ( not secret courts ), non-arbitrary detention, even regular elections for granted.
I totally agree with you that the UK is not Iran and there is too much hyperbole - but at the same time the current government is trying to criminalise legitimate protest, cancelling elections and trying to remove trial by jury for a substantial set of things ( the ultimate protection against an authoritarian state ).
As an example, it's very telling that the government ensured that in all the Assange legal proceedings it never went before a jury.
The current government creating all these precedents, in the shadow of the prospect of a potential Reform government is something I think we should all be concerned about.
Tell me about it, that Jury thing in particular was shocking to hear, that they’re considering throwing aside an ancient right in the name of expediency and clearing a backlog, as if it was a minor detail and not the basis of the system of justice.
