Who is responsible for conducting background checks for firearm applicants in Hawaii?

The County Police Chief in Hawaii is responsible for conducting background checks for firearm applicants. This is to ensure that individuals who are applying to possess firearms meet the necessary requirements and do not have a history that would disqualify them from owning a firearm according to Hawaii state laws. The other options, such as the FBI, Hawaii State Sheriff's Office, and Department of Homeland Security, do not have the specific responsibility of conducting background checks for firearm applicants in Hawaii.
