Illinois State Rep. Kelly M. Cassidy (D-14) introduced a bill on Feb. 5 that would require gun owners to register every gun they own. According to the bill, called the Firearms Registration Act (HB4715), this would not just apply to new purchases but Illinoisans would also need to register guns they already own.

The bill’s synopsis explains [emphasis added]:

“Creates the Firearms Registration Act. Provides that every person in the State must register each firearm he or she owns or possesses in accordance with the Act.”
