One of the policy changes introduced by the Omnibus Public Safety and Justice Amendment Act of 2009 made it easier to detain pretrial defendants charged with certain offenses, mostly dangerous or violent crimes. This report examines whether detention of these defendants increased following passage of the Act. Trends in the pretrial detention of violent and dangerous defendants indicate that detention was on the rise before the Act and continued to rise after its passage. Results suggest that pretrial detention for dangerous and violent defendants without weapons charges rose after passage of the Act, but those with associated weapons charges show no change.
