The constitution does NOT intend to secure rights of citizens. It describes what rights government may usurp. As a matter of fact Madison was reluctant to add a bill of rights because he felt that people would come to the conclusion that you (and in fact many modern Supreme Court Justices) have, namely that the rights in the bill of rights are the ONLY ones expressly protected. Madison included the 9th and 10th amendments for exactly this reason.
[Amendment IX]
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
[Amendment X]
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
