Do not make the mistake that "legal = ethical" and vice-versa. While I am not an American and probably have not studied your history as much as many of you have, the actual "Declaration of Independence" may have been illegal, but at its heart is not "unethical". The Nuremberg Laws and "Jim Crow" type laws & enforcement may have been "legal", but they are certainly not "ethical". Smoking or possessing marijiana is illegal (even though I don't do it) and you may be supporting organized crime if you purchase it, but does that automatically make it "unethical"?
