Wife and I were having this discussion the other day. I'm not a felon and don't really even know many, so I have no skin in the game, but I believe they should get their rights back. She thought more along the pathway, which I would agree with if there was some sort of violence that led to them being a felon. You don't lose your 1st amendment, or 4th, or 5th, or any other right after you've served your time, so why lose the 2nd? I didn't see anywhere in the bill of rights that you should be stripped of all rights for life after paying a debt to society but I could have missed it? ACB will make a great justice.
The permanent federal 2A ban for felons is a recent thing only being enacted with the GCA of 1968, 52 years ago. Prior to that it was standard practice that once a sentence and probation was complete a person returned as a full citizen on the federal level. However, many states had such restrictions. Historically as part of the "Black Codes" that were put in place during times of slavery and later carried forward into Jim Crow.
While I won't adopt the attitude of the left and say systemic many of our "reasonable" gun control measures are historically racist.
