Although... He gives us both the pro and the con argument.
Treating gun rights like a license to drive is a dead end. Licensing is just a pretext to confiscation, IMHO. There is no right to drive enshrined in the Constitution. He says it's not a perfect analogy, so I do have respect for that. Still, he does acknowledge the real reason—protection from government tyranny and a human’s innate right to protect themselves.
He's probably seen way to many killings in the ghetto, but they way out of that is to go after the bad guys, not everyone who obeys the law. Consider that ghetto killers' victims are usually other ghetto people (am I racist for putting it that way?), it would be a great help to that part of our society, too.
Bottom line for me Carson has an open mind on the second amendment. This is after becoming an accomplished marksman. Not a deal killer for me.
