The bill amends the District of Columbia Official Code to impose mandatory pretrial detention for individuals charged with crimes of violence or dangerous crimes, removing them from the pretrial release framework. It also establishes mandatory post‑conviction detention for the same categories, ensuring that convicted persons remain in custody until the completion of their sentence. The amendments broaden the definition of dangerous and violent crimes to include first‑degree burglary, robbery, and offenses involving dangerous weapons. In addition, the legislation requires cash bail for defendants charged with public safety or order offenses such as failure to appear, obstruction of justice, rioting, or non‑first‑degree burglary/robbery. The new bail provisions allow for secured or unsecured appearance bonds and grant sureties the right to arrest the defendant if the bond is breached. The bill also modifies pretrial release conditions, presuming that no release conditions will assure safety when probable cause exists for certain violent or dangerous conduct. These changes aim to tighten bail procedures for public order crimes while ensuring that high‑risk defendants are detained appropriately. The Act applies to offenses committed in the District of Columbia on or after a date 30 days following enactment. It includes conforming amendments to align definitions and procedural requirements with the new mandatory detention and bail rules. The overall intent is to enhance public safety by ensuring that individuals who pose a threat are detained before trial and held after conviction, while tightening bail for public order offenses.
