The Oregon Senate Judiciary Committee heard public testimony Tuesday morning for an omnibus bill combining several proposed gun laws. Opponents of Senate Bill 978 sign in before public testimony at the Capitol in Salem, Ore., Tuesday, April 2, 2019. An amendment to the bill before the Senate judiciary committee requires safe storage of firearms, allows retailers to refuse some gun sales and more. If passed, the bill would give firearms dealers the option of raising the minimum purchase age to between 18 and 21 and require firearms to be securely stored when not in use. Depending on the specifics, violations of the safe storage law could be a Class A violation, a Class B misdemeanor or a Class A misdemeanor. The bill also places restrictions on the sale of unfinished and 3D-printed firearms — sometimes called “ghost guns.” Other rules in the bill would add hospital reporting requirements for patients injured by firearms and would allow colleges and universities to ban firearms on campus. Experts and advocates both for and against the legislation packed the Capitol hallways Tuesday as they waited to testify. Many people also submitted written comments on the omnibus bill. The House of Representatives will hold hearings on a similar bill.
