Usurpation of one's sovereignty and the origins of the death tax.

On July 1, 2010 ABC News (finally) provided to the American people what is presumed to be "the official story" about what happened to Jerry and Joe Kane and two Arkansas policemen who were shot dead on May 20th.  But WHY is there such an emphasis on Jerry's claim to being "sovereign"?  Because our constitutional Form of government is a contractual form of government aren't ALL American's "sovereign"?  If individual sovereignity was not the intent for the people of our nation, what would have motivated our individual and collective 'states' to implement the "castle doctrine"?

Origins

The American interpretation of this doctrine is largely derived from the English Common Law as it stood in the 1700s. In Book 4, Chapter 16 of William Blackstone's Commentaries on the Laws of England, he says:

And the law of England has so particular and tender a regard to the immunity of a man's house, that it stiles it his castle, and will never suffer it to be violated with immunity: agreeing herein with the sentiments of ancient Rome, as expressed in the works of Tully; quid enim sanctius, quid omni religione munitius, quam domus unusquisque civium? For this reason no doors can in general be broken open to execute any civil process; though, in criminal causes, the public safety supersedes the private. Hence also in part arises the animadversion of the law upon eaves-droppers, nusancers, and incendiaries: and to this principal it must be assigned, that a man may assemble people together lawfully without danger of raising a riot, rout, or unlawful assembly, in order to protect and defend his house; which he is not permitted to do in any other case.

Could it be that history has repeated itself?  And that the sovereign people of our nation have been collectively schmoozed by the likes of Pharaoh Rikayon who "cunningly usurped the government of Egypt" by exacting "a tax from the dead"?
