Another interesting series of data points from the 2005 report on Brady check stats:
http://www.ojp.usdoj.gov/bjs/pub/ascii/bcft05.txt
* 1.6% of the 8.3 million applications for firearm transfers or permits in 2005 were rejected by the FBI (66,700 applications)or State and local agencies(65,200 applications).
* The Bureau of Alcohol, Tobacco, Firearm and Explosive's(ATF) field offices investigated 9,575 National Instant Criminal Background Check System(NICS)denials that were referred by the FBI in 2005.
* In 2005 U.S. attorney offices accepted for prosecution 135 NICS denial cases investigated by ATF.
In 2005, 130,000 folks were denied legal access to a firearm, of which sixty seven thousand purchases were blocked by the FBI. Of those sixty seven thousand FBI-blocked transactions, less than ten thousand represented denials worthy of ATFE investigation and only 135 were cases suitable for Federal prosecution. H'okay......
161,000 appeals of denials from 1999 to 2005; 57,000 reversed
I'm sure that the more than TEN THOUSAND folk who were inappropriately denied the right to purchase a firearm every year didn't mind being inconvenienced; it did result in one hundred and thirty five Bad Guys getting their just rewards.
