Prohibit government entities and officials from keeping certain lists relating to the ownership of firearms and prohibit using merchant category codes to distinguish firearm retailers

LB 686 prohibits government entities from maintaining lists of privately owned firearms or firearm owners, except during criminal investigations. It also bans payment networks and retailers from using merchant category codes to identify firearm retailers or transactions involving firearms. The bill requires the Attorney General to enforce these rules by investigating violations, issuing corrective notices, and imposing civil fines of up to $1,000 per violation for non-compliance. This law directly affects government agencies, payment processors, and retailers handling firearm sales in Nebraska.
