Just as every person within our jurisdiction (ie: subject to our civil and criminal laws) must pay taxes on inccome or property, comply with our criminal laws, can sue or be sued in our courts, can be subpoened or compelled to attend court or appear before a law enforcement agency or grand jury or any other aspect of participation in daily life, then that same person is entitled to whatever any other person would.
We can agree, disagree, like it or not, but our Constitution does not allow it to be any other way.
