Free gun safety locks are now available at all 15 open public library branches in Anne Arundel County. The pilot program began in April when gun safety locks were made available to county residents at three public libraries. By June, the program grew to six libraries due to its popularity. County residents who are 18 years old and up can receive up to two gun safety locks per household, per day. No proof of residency is required. Listings for operating hours and directions can be found at library branches.
