What degree of proof is required for a warrantless arrest?

For a warrantless arrest, the officer must have probable cause—a reasonable belief, based on facts and circumstances, that the person has committed, is committing, or is about to commit a crime. This is more than a mere hunch but not as high as the proof needed to convict. For example, seeing someone commit a crime or having reliable information that a person just committed a crime can create probable cause to arrest without a warrant. Reasonable suspicion, by contrast, just justifies a brief stop or investigation, not a full arrest. Preponderance of the evidence is the civil standard used in lawsuits, not the criminal arrest standard. Beyond a reasonable doubt is the standard used to convict someone in court, not to justify an arrest.
