Why are those who so ardently defend the Constitution not speaking up when police keep forcibly removing those who are trying to exercise such a clear and simple right?

Amendment I

Congress shall make no law ... prohibiting the free exercise thereof ... the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

Despite quotes to the contrary, I do not see anything in these words that provide for an exception to this right.

Full wording:

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

Whether you agree or don't agree with the Occupy movement, protecting the First Amendment seems like a no-brainer.
