Bill of Rights. "Feds only"?
And, I find it funny that some people claim that the Bill of Rights is "only binding on the federal government". Nonsense.
What the Bill of Rights did was to recognize that there are things no other person is allowed to do to you. No matter their justification. "Government" is nothing but people- so forbidding government to do something means it is recognized that no individual has the right or the authority to do those things to any other individual. You can't eliminate this truth by paring a "government" down to one person or by piling people together until you can call it a "government".
No government can do what is wrong for an individual to do without being in the wrong, and no individual can do things that are wrong for "government" to do, either. Because there is no "government"; there are individuals. The Bill of Rights just recognizes that some things are wrong for one person to do to any other person. But it only makes it a crime for government to do those things.
