LEOSA is often incorrectly referred to as "H.R. 218". The act was introduced during the 108th Congress as H.R. 218 and enacted as Public Law 108-277. The law was later amended by the Law Enforcement Officers Safety Act Improvements Act of 2010 (S. 1132, Public Law 111-272), and Section 1099C of the National Defense Authorization Act for Fiscal Year 2013 (H.R. 4310, Public Law 112-239). It is codified within the provisions of the Gun Control Act of 1968 as 18 USC § 926B and USC § 926C.
