Stephen Street has served as Louisiana's Inspector General since 2008, and is the immediate past President of the National Association of Inspectors General (AIG). The mission of the Louisiana Inspector General is to investigate white collar criminal and public corruption cases, and to root out and prevent fraud and corruption in government.

Mr. Street received his law degree in 1989 from the Paul M. Hebert Law Center at Louisiana State University. Most of his 30 plus years as an attorney have been spent in the field of criminal law at the state and federal levels, first as a criminal staff lawyer with the Third Circuit Court of Appeal in Lake Charles, and then later both defending and prosecuting serious criminal cases. Mr. Street has extensive experience as lead trial counsel in a wide variety of cases, from capital murder to complex white collar and economic crime.

Since becoming Louisiana's Inspector General, Mr. Street has overseen the transformation of the office from an internal audit shop into a fully functioning statutorily empowered law enforcement agency. Experience has demonstrated that the most effective way to ensure integrity in government is to hold those who violate the public trust criminally accountable whenever the evidence warrants. In addition, other desired outcomes, such as improved internal controls and safeguards designed to better prevent and detect criminal fraud and corruption, are often achieved more quickly and with greater public support in the wake of successful criminal prosecutions. The Louisiana OIG therefore focuses primarily on fraud and public corruption investigations, with results that speak for themselves. Since transitioning to law enforcement, the Inspector General has experienced great success, working numerous criminal cases, both independently and with law enforcement partners.
