Suspects detained under initial law enforcement arrest authority. Establishes the 48-hour Gerstein clock for judicial determination of probable cause without unreasonable delay.
Criminal proceedings demand progressively heightened factual standards across stages:
| Standard | Threshold Level | Required Procedural Milestone |
|---|---|---|
| Reasonable Suspicion | Articulable facts (> hunch) | Terry stop, temporary investigatory detention |
| Probable Cause | Substantial factual probability | Warrantless arrest, Gerstein review, search warrant |
| Prima Facie / Substantial Evidence | Plausible criminal case | Preliminary examination bindover / Grand Jury indictment |
| Beyond a Reasonable Doubt | Near-absolute certainty (>99%) | Formal trial verdict, final adjudication of guilt |
Criminal accusations and warrantless arrests are procedural actions, not determinations of guilt. Under constitutional due process, all individuals remain presumed innocent unless and until convicted in a court of competent jurisdiction under the proof beyond a reasonable doubt standard.
