Special Inspector General for Law Enforcement Act This bill establishes the Office of the Special Inspector General for Law Enforcement. The bill sets forth the duties of the office, including investigating racial profiling, officer misconduct, use of force, use of deadly force, or pattern or practice of unconstitutional misconduct involving federal law enforcement agencies or officers; and use-of-deadly-force cases referred by state and local law enforcement agencies. The bill requires a state or local government that receives funding under the Edward Byrne Memorial Justice Assistance Grant program or the Community Oriented Policing Services grant program to have in effect a law establishing a process by which use-of-deadly-force cases can be referred to the office for investigation.
