Unalienable / Inalienable
I never realized that "Unalienable / Inalienable" was a big deal, until I saw this movie.
There are, actually, multiple copies of the declaration in which the words are different.
This website:
http://www.ushistory.org/declaration/unalienable.htm
give a great breakdown of this debate.
It seems Mr Adams definitLEE may have spoken to the printer about it.
That site also give a lot of good information about the document, the signers, timelines, etc., for anyone who wants to know more after watching "1776."
