A new gun law is poised to keep domestic violence victims safer. The new Louisiana law bans those convicted of domestic abuse from owning firearms for four years in hopes the law will protect victims of violent abuse. Someone who has been convicted of the crime or who is under a protection order either can sign a court-sworn declaration that he or she doesn't own weapons or can sign a declaration in a sheriff's office that any weapons will be given to a third party or surrendered to the sheriff's office.
