Where did you get the numbers that a 100,000 guns make it through back ground checks ?Do most know that the current law allows three days? How many have had to wait 3 days because of federal law? I bet the vast majority here have not had to wait at all. They fill out there background and move on.
There are so many nuances that take time to figure out. Weather or not a person is prohibited is not cut and dry. There are several states (Montana being one) that has automatic restoration of firearms rights for some felonies. Domestic Violence conviction is not always a prohibitor depending on the state of conviction (Wyoming US v Hays). Temporary restraining orders may or may not be prohibitors. The list goes on.. For the vast majority of people, the stats are well over 98%, their backgrounds checks go through without any delay.
Also for clarification...this does not give ATF any more power over anything. This law would have absolutely nothing to do with the ATF.
Well over 100 K times a year, prohibited people are getting firearms through the NICS delayed denial. If there is not a resolution to the federal background check within 3 days the firearm is transferred. This is a significant drain on LE resources wherein they are then required to go retrieve the firearm. These retrieval’s are often contentious and dangerous for LE. The 30 days is intended to help prevent these from happening.
Many of the individual states have prolonged waiting periods that have nothing to do with the federal NICS process. It seems like people are confusing the two processes. When I moved to VA, I had to wait 30 days to pickup my most recent firearm. It sucked! I still had to go through the federal NICS background. It took all of about one minute...after the state mandated 30 days.
Good luck in the draws.
