I’m not sure what Carson hoped to accomplish by highlighting past violent behavior even if it was in his teens. It’s a great thing that he turned himself around and became a very accomplished surgeon, he is to be commended and provides an example for all troubled teens. But, to me it comes back around to bite someone hoping to be elected President. People will always wonder about his mental state.
It was already in his books. It is not something new.
He is trying to show how far he came. Maybe as inspiration.
OTOH, if he didn’t talk about it first, the media would trumpet it as if he were trying to hide his past. And he is not. However, he is not my choice for president. I would make him HHS secretary or Surgeon General.
