1.In MLks letter he states: “: An unjust law is a human law that is not rooted in eternal law and natural law. Any law that uplifts human personality is just. Any law that degrades human personality is unjust. A” . we can tell the difference by if it degrades us, maybe even separates us. 

2.This is an important distinction and I think MLK did a good job at describing the difference, laws are put in place to keep order and tame us if needed, but they should never take away our rights based on color, religion, or anything like that. It most definitely can effect our politics, and it did for years, centuries even. If most people in politics are white, like it used to be, they can control a lot of things by being racist, by not wanting so see the success of a certain person, in this case they arrested MLK for being Peaceful! 

3. One unjust law would be Bail reform, that if you are given a bail and can cover it, your out. Depending on what you did of course. But what if you dont have that money? There is a lot of people that don’t, its unfair in the sense it doesn’t apply to every human because not every human has the same income. Now a Just law would be something like Civil rights act, something that MAKES sure we all know we are equal, all humans, it doesn’t sort into rich or poor, or divide based on color, it all comes down to our civil rights.
