Jefferson and Adams weren't involved. Both were abroad as ambassadors to France and Britain respectively.
Adams was consider the leading constitutional theorist of his time. His views mattered. Throughout his government service and thereafter, he criticized the Constitution in private correspondence.
Jefferson was just as displeased. Until it was added, he objected to omitting a Bill of Rights. He and Madison wanted additional provisions neither got.
They urged "freedom from monopolies and commerce (corporate giants) and "freedom from a permanent military (standing armies)." Adams and Hamilton disagreed and prevailed.
Why does all this matter? Because it's preamble to America today. From inception, it's been more hypocrisy than democracy. Now, in fact, what few rights remain are threatened. They're eroding fast en route to disappearing altogether.
Targeting Assange is one of many examples. Doing so means we're all threatened. Free expression and dissent are endangered. Revealing ugly truths power brokers want suppressed risks putting your freedom and perhaps life in danger.
Assange is a political refugee. Since mid-June, he's been holed up in Ecuador's UK embassy. In mid-August, he was granted political asylum. Britain's acting on America's behalf. So is Sweden.
Alleged rape charges were fabricated. A Swedish prosecutor found no wrongdoing and dismissed the case. Another on orders from her own government or perhaps Washington reopened it and issued an extradition order.
