I do not accept you're view that a written and Entrenched Bill of Rights and Constitution in Supreme law, would snuff out our liberty. It would make them imperviuos to the passing whims of Westminster.
I have never understood the pride the some Englishmen have in the legal system, it's antiquated and allows for grave abuses of human rights. The secercy act is very disturbing, who knows what the govt. has done.
