Title 34 of the United States Code is a non-positive law title of the United States Code with the heading "Crime Control and Law Enforcement." Released on September 1, 2017 by the Office of the Law Revision Counsel of the United States House of Representatives, it contains "crime control and law enforcement programs or activities in which the Attorney General or the Department of Justice (or one of its components) have been given primary responsibility." Much of the law transferred to Title 34 were laws editorially classified to sections of Title 42 or set out as notes to Titles 42, 18, and 28.
Prior to 1956, Title 34 outlined the role of the United States Navy in the United States Code. It was repealed on August 10, 1956 by an act of Congress when the laws within it were either eliminated or moved into the new revision of Title 10.  
The Omnibus Crime Control and Safe Streets Act of 1968, as amended, is partly codified to Chapter 101 of Title 34.
The Violent Crime Control and Law Enforcement Act is partially codified to Chapter 121 of Title 34; however, those portions that amended the Omnibus Crime Control and Safe Streets Act of 1968 are found in Chapter 101 of Title 34, while still other portions of the Act are in the other portions of the U.S. Code or uncodified. The Violence Against Women Act of 1994 (VAWA) was enacted as Title IV of the Violent Crime Control and Law Enforcement Act. Where VAWA amended the Omnibus Crime Control and Safe Streets Act of 1968, it can be found at Subchapter XIX of Chapter 101 of Title 34. Where VAWA did not amend an existing Act or amend a positive law title of the U.S. Code, it can generally be found in Subchapter III of Chapter 121 of Title 34.
The Juvenile Justice and Delinquency Prevention Act of 1974, as amended, is partly codified to Chapter 111 of Title 34.
Some provisions of the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act are codified to Chapter 305 of Title 34.
