10. Police techniques.

Internal law enforcement detection and investigation methods are generally exempt under section 552.108. In Ex parte Pruitt, 551 S.W.2d 706, 710 (Tex. 1977), the Texas Supreme Court held that the Act excepts law enforcement information if release "will unduly interfere with law enforcement and crime prevention."  In Tex. Att'y Gen. ORD-531 (1989), the Attorney General advised that detailed portions of a police department's "use of force" procedures are excepted from disclosure under the Act because it "is reasonable to conclude that knowledge of these detailed guidelines would place an individual at an advantage in confrontations with police officers and would increase his chances of evading arrest or injuring the officer or other persons." However, other portions of the procedures that only restate generally known common law, constitutional, or Penal Code provisions are public.
