Lessons learned...
-Christian Puritans were a bit wacky. Most of the local government was run by the Puritans at that time, and they enforced terrible punishments on these "witches". Religious extremism, even Christianity, can be cruel and inhumane.
-The early courts made most of their decisions about "witches" on the confessions of whistle-blowers. People were considered guilty by association. Anyone who denied accusations would have been tortured in terrible ways, until the person submitted to agree to a confession. Judges believed that this method was a highly effective means of finding out the truth in a case. Nowadays, people are innocent until proven guilty. Everyone, no matter how strong the evidence is against them, deserves a fair trial and basic human rights until they are proven guilty.
-Besides the fact that the early colonials were religious extremists, it should also be reminded that the judicial system at this time was basically unchecked by the government because there was no binding Constitution at the time. Only the King of England could have overruled a judgment, although it is hardly likely that he much about a few peasants across the Atlantic Ocean who were accused of being witches. The wonderful thing about the Constitution, when it was finally designed, is that it written using secular language, that people of any religion could commonly respect. "We hold these truths to be self evident" regarding human rights, allowed people to look beyond what their religious teachings may suggest about crime and punishment, and instead use their brains and values to agree with the obvious notion that all humans should be treated with a certain measure of respect.
-Without the Constitution worded the way it is, it would be very easy for America to slip back about 500 to 1000 years in civilization. Without the separation of Church and State, the Church would seek to re-institute itself as a divinely inspired Theocracy. Although this type of government was once very powerful (ie. Holy Roman Empire), but it was extremely barbaric. The Theocracy values the "divinity" of the Pope so highly, that anything he decides becomes divine law, regardless of how obviously inhumane it may seem. With our current Constitution, not only are our human rights protected, but also our rights to vote, elect leaders, and maintain democracy are protected.
-Early colonists eventually realized that lack of freedom they had by remaining underneath the rulership of the King of England. They instigated the Revolutionary War because they desired liberty.
