LOL... Americans never had any rights to begin with... sure, you might BELIEVE you have rights, but belief doesn't make it fact.
Supreme Court rules to protect police from lawsuits over violating Miranda Rights.
Well, by definition EVERYONE has rights by virtue of being a human being. That's why they're called human rights. Governments often curtail and limit those rights in practice, but they still exist.
Yes that's true. Essentially in any system Rights are only as sound that the class and power structure that people live under. These things underpin Rights, though they shouldn't, and if the power structure changes, these Rights are at risk, like what is happening in the US now.
