In this Feb. 27, 2014 photo, Julian Ramirez, left, chief of the civil rights division with the Harris County district attorney, and investigator Kirk Bonsal discuss the merits of a shooting simulator used to teach grand jurors about the use of deadly force, in Houston. The simulator projects on a screen various scenarios, including a confrontation with a carjacker, where grand jurors use a specially modified gun and have to decide whether to fire in self-defense. But critics argue that it puts grand jurors in a pro-law enforcement mindset. One Houston defense attorney recently unsuccessfully challenged the simulator’s use, calling it mind manipulation.

The interactive way of illustrating the legal concept of deadly force is part of the unique training that Houston-area grand jurors can receive before they begin hearing cases.
