Which standard applies to a warrantless arrest?

Probable cause is the standard that justifies a warrantless arrest. It means there are enough facts and circumstances to lead a reasonable officer to believe the person committed or is committing a crime. This threshold is higher than a mere hunch or guess, but it does not require proof beyond a reasonable doubt. For example, witnessing someone shoplifting or receiving a reliable report with corroborating details can provide probable cause to arrest without a warrant. Reasonable suspicion is a lower standard used for stops and brief detentions, not full arrests. The other standards—preponderance of the evidence and beyond a reasonable doubt—are used in court to decide liability or guilt, not to authorize an arrest in the field.
