> Get rid of jury trials for northern Ireland for a few years
I believe we still have Diplock courts. They were actually put in place because internment without trial was considered too draconian. The kind of thing that would never occur with a constitution (give me a G...)
> Californian cities can take their own people's guns away
How does that work? Is California accepting that the 2nd amendment put in the bit about a militia for a reason or something else? I mean, the US Constitution isn't meant to be a state by state menu is it?
> You have to have at least minimal evidence that somebody did something before you can ransack their house.
I believe you have to have reasonable cause. You don't actually need any evidence. And, as you point out, you've all had a few years to drum up some excuses when it becomes inconvenient.
I'm sure having a constitution is comforting and all but, in reality, you're in exactly the same boat as the UK and for exactly the same reasons. We have checks and balances too.
And when the state, in its infinite wisdom, chooses to bend them, we sometimes get quite annoyed (the UK version of angry).
