yes there is a way to amend the constitution but I have seen no amendment to the second,it clarly sated tha the right of the people to keep and bare arms SHALL NOT BE INFRINGED.it says nothing about BUT.and the scotus did not rule on regulations they ducked it.and ruled only on a narrow point.whats the 15 amendment say, can you have a partial civil right.all the gun laws were put in place to prevent a class or group of people from having arms.
the blacks were one the political parties another.all intended to prevent the defence from attack.
