So your presumption is that all the people calling for background checks and that have drafted and passed a complete background check law have not considered any of this, or looked at any data? And despite not actually knowing yourself you're comfortable dismissing it as something you "highly doubt"?
I have tried to find numbers on this after I made my comment and couldn't come up with anything.

Yes, generally because the people proposing gun laws know nothing about guns.
I have watched national politicians tell townhalls that it's perfectly legal for someone to order a gun online right to their door without a background check, that is a felony.
I have watched them tell people that fully automatic guns are easy to obtain, which they are not.
I have watched them tell people that banning the AR-15 should be our #1 priority, when in reality more people are punched and kicked to death each year than are killed with rifles.
So yes, politicians generally talk out of their @$$ to pander to their bases and get votes. They are not experts on most subject matter so I wouldn't expect them to have any info that isn't widely known.
