Establishes rebuttable presumption of pretrial detention of defendant charged with aggravated assault of law enforcement officer.

S 3351 establishes a rebuttable presumption that defendants charged with aggravated assault against law enforcement officers must be held in pretrial detention unless they can prove otherwise. This bill amends New Jersey's criminal justice law to add "aggravated assault of a law enforcement officer" to the list of offenses triggering this presumption, alongside existing crimes like murder or life-imprisonment offenses. Defendants facing these charges would need to demonstrate by a preponderance of evidence that release conditions could reasonably ensure court appearance and public safety. The law does not automatically detain these defendants but shifts the burden to the defendant to rebut the presumption at a hearing. This directly affects individuals charged with this specific violent offense against police officers.
