The Omnibus Crime Control and Safe Streets Act of 1968 (Pub.L. 90-351, June 19, 1968, 82 Stat. 197, 42 U.S.C. § 3711) was legislation passed by the Congress of the United States that established the Law Enforcement Assistance Administration (LEAA). Title III of the Act set rules for obtaining wiretap orders in the United States. It has been started shortly after November 22, 1963 when evidence in the assassination of President John F. Kennedy increased public alertness to the relative lack of control over the sale and possession of guns in America.

The Omnibus Crime Bill also prohibited interstate trade in handguns, increased the minimum age to 21 for buying handguns, and established a national gun licensing system.[2] This legislation was soon followed by the Gun Control Act of 1968, which set forth additional gun control restrictions.
