if he was a 2A absolutist, no restrictions at all would be promoted.
Not only ex-cons, but no need for any kind of permitting, concealed carry (why not out in the open?), anything.
But I think some rules are OK. I can see allowing ex-cons, perhaps after a certain period. I knew a terrific ex-con 20 years ago, a machinist who did a lot of my prototype work, and we had lots of talk. He was so incredibly conservative and so honorable in his maturity. He wasn’t allowed to vote and that came up. Ok, I can see not allowing vote anymore, but why not firearms after he’s been out say 5 years?
