You really don't get it, do you? The people have all the power and gave some to the state and Federal governments. The people were NOT given power by the Constitution. They agreed to relinquish some of the power they had, not near as much as our "modern" politicos think, to the government. We (the people) gave the power to the government and we can take it away.
If there is to be any punishment, then that is the reserve of the [freely elected] government [by the people]. To give the American people unrestrained free rule is insane. People do not have the right, nor should they, to take the law into their own hands.
