I don't know what he means.He is fine with the "highly vetted and most qualified" having them. Isn't that the NY system? "Highly vetted and most qualified" - meaning: greased the right gears? Nothing for the poors.
"highly vetted and most qualified" sounds good and is a "reasonable" 5 word answer to a complex question when you don't have everything reasoned out yet.
See also "common sense", "obvious", and "effective". Without more information these mean nothing.
What we do know is that he didn't say "ban them all" or "the 2A is for hunting".
I think this is a realm he hasn't crawled into yet. His opinion is likely to change as he learns more.
