A great many countries have a Bill of Rights, but there is usually a wide gulf between what is officially supposed to be done by police and courts and government, and what is actually done behind closed doors but isn't spoken of or reported on in the mainstream media.

You could call it the "hypocrisy gap". This is so not only in the USA, but in virtually every other country on Earth, including my own.

A Bill of Rights in itself is not enough (although it's a good start). You must also have a government, police, and judiciary who are honest enough to obey it to the letter and in every case, no matter whose interests are involved.

That, in practice, has turned out to be virtually impossible.

What's a lot worse, though, is a place that HAS no Bill of Rights. So we can count our blessings, I guess.
