What will happen if the abuser tries to purchase a gun?
Before purchasing a gun from a licensed firearm dealer, all buyers must undergo a criminal background check that is processed through the National Instant Criminal Background Check System (NICS). The National Instant Criminal Background Check System is used by federal firearms licensees (FFLs), such as firearms dealers or pawnbrokers, to instantly determine whether someone is eligible to receive (own, possess, transport) firearms or explosives.1 If the abuser has a qualifying protection order against him/her, or has been convicted of a felony or domestic violence misdemeanor in any state, those records should be in the NICS, which should prevent the abuser from legally buying a gun. Not all states have automated record keeping systems, making it more difficult to process the criminal background check, and some criminals and abusers do slip through the system. Also, it is important to know that background checks are not required for private and online gun sales and so in those situations, the seller is not looking in the NICS.
If the abuser is able to purchase a gun and you believe that s/he should not be able to have one under the law, you can alert the police, and ask that his/her gun be taken away and perhaps the police will investigate. Generally, it is not a good idea to assume that because the abuser was able to buy a gun, it is legal for him/her to have one.
