Irrelevant. There is no functional difference.
The end result is that a bunch of random Joe Rambos will get to carry guns, and those who don't make the grade, and want to go armed, will carry guns anyway.
The problem in the US is NOT, repeat NOT down to some imaginary difference between those who do and those who don't have carry permits, its down to the number of guns and how easy they are to get.
There is a direct correlation between the the number of shootings and the strength of the gun laws... the tighter the laws, the lower the shooting rates

"....from 2010 onwards, the gap between permissive and restrictive states started to widen, with rates falling in restrictive states and rising in permissive states.
Levels of gun ownership were also significantly associated with mass shooting rates.
After taking account of key factors, a 10 unit increase in state gun law permissiveness, as defined by the scale, was associated with an 11.5% higher rate of mass shootings.
These findings held true, even when different factors were accounted for and whether or not the mass shootings were perpetrated by someone in a close relationship with the victims.
And a 10% increase in gun ownership was associated with a more than 35% higher rate of mass shootings."
