Wow, that first paragraph about the constitution not having any protection against government is pure truthiness. 

The constitution does not grant or list the rights of the People either in body or in the first ten amendments. 

The federal constiutiton DOES grant the and list the rights of the government.  Art 1 section 8 lists the 17 powers of congress.  Article one section 9 restricts how those powers can be exercised.  And the first 10 amendments further restrict how those powers can be exercised. 

They are written from the people to Congress explaining how the Congress is limited.  "Congress shall make no law..." 

Read the preamble to the first ten amendments... it's all right there.
