Unlike a preliminary hearing, held in court with the defense side present, the grand jury does not make its decision in the context of an adversary proceeding. Rather, grand jurors see and hear only what prosecutors put before them. (Prosecutors technically have an obligation to present “exculpatory” evidence—evidence that suggests that a defendant might not be guilty—though there is not much other than the prosecutor’s conscience to enforce this rule.)

In part because there’s no one on the "other side" to contest the prosecutor’s evidence, grand juries almost always return an indictment as requested by the prosecutor. According to a U.S. Department of Justice study on plea bargaining, “Grand juries are notorious for being ‘rubber?stamps’ for the prosecutor for virtually all routine criminal matters.” (Plea Bargaining: Critical Issues and Common Practices, by William F. McDonald, (U.S. DOJ, National Institute of Justice, 1985).)
