Licensed gun dealers have no requirements to report multiple sales of long guns, like the semiautomatic assault style weapons sought by terrorist organizations. So someone can buy long guns by the hundreds and there is no requirement that these sales will be reported to law enforcement.
Licensed gun dealers have to report to federal law enforcement whenever someone buys two or more handguns in 5 business days. But if someone buys a gun, say, every six days the sales do not get reported.
Licensed dealers are allowed to sell guns after three days even if a background check is not completed. As many as 5 percent of background checks are not complete within 3 days. During a 2 1/2 year period, more than 10,000 felons were able to buy guns because their background check was not completed in 3 days.
Police can only trace a serial number back to the first retail sale of a new gun by a licensed gun dealer. Therefore, if someone buys a secondhand gun from a "private" seller, the gun can't be traced back to its illegal seller or the purchaser.
If federally licensed gun dealers fail to report stolen or missing guns, they generally face only misdemeanor charges even though thousands of guns are stolen annually from gun stores. The rifle used by the metro DC snipers was allegedly stolen from a gun store, the same store that "lost or misplaced" 238 guns in three years.
Gun owners are not required to report thefts of their guns to law enforcement. Nearly half a million guns are stolen annually.
Common carriers -- like trucking companies -- do not have to report missing gun shipments.
Licensed dealers convicted of felonies may continue to conduct business through all appeals. which and take a decade
No gun manufacturer has any policy restricting sales of their guns to dealers or wholesalers with a history of selling guns used in crime.
Federal inspectors are barred from conducting surprise inspections of a gun dealer more than once a year and they have no power to impose fines or suspend licenses even if the inspectors have evidence that the dealer is continuing to sell guns that are used in crime.
