When I think of the tyranny of the majority I think of people with disabilities who, if the majority wanted to, could be ‘euthanised’ for being a drain on society. I don’t mean to say that we should be giving ‘rights’ to the so-called oppressed minority.

Just because the majority wants something, doesn’t make it right.

I would like to make a few comments on your post though.
you say “So long as the state can be trusted to pass laws that are in the common interest and, simultaneously, do not subject minorities to the tyranny of the majority,”

Personally I’m kind of fedup of this talk about majorities tyrannizing minorities. The reverse can also easily be true, many dictators throughout the world have been supported by minorities suppressing a larger group, and we see with the way Muslims intimiated the British media with regard to the Mohammad cartoons that even a very small minority can have a big effect on once treasured freedoms.
I know you said common interest, but as the balkanisation continues it may not be clear what that is.

Agree there is never an excuse to imprison ‘us’ without trial, ‘Us’ being citizens, but foreign nationals I’m not so sure…
You are not forgetting that Islamic extremists have declared war on us are you?
In World War 2, if a ‘foreign national’ German turned up on your doorstep in the middle of the night, you’d want the government to take some kind of action even without ‘evidence’ that he was planning to do you harm wouldn’t you?
If someone bad from within Britain does something that the government needs to charge them with the police etc have plenty of ways they can pursue the case, but someone who arrives here from Afghanistan, where is this ‘evidence’ going to come from?

I think the rules need to be different for nationals and non-nationals based on the ability to get evidence.

Agree regards Jury trial, but another point is if the Jury are not able to understand the case then that is the fault of the government for the over complicated tax , red tape and whole bureaucratic system, so its very possible to solve the problem without scrapping Jury trial.

You didn’t mention what I think will be one of the worst loses of liberty, road pricing.
This with the combination of ID cards will mean the government can follow your every movement. No problem for most people but as you say, for some if the government gets tough they could make life hell.
