searches and seizures and requires that warrants be supported by probable cause. It is
the foundational amendment governing law enforcement search and seizure authority.

B. Being fingerprinted at the station
,C. Custodial interrogation by law enforcement

B. Reasonable grounds based on articulable facts to believe a crime has been
committed

D. A written authorization from a judge to make an arrest
E. The testimony of at least two witnesses identifying a suspect
✓ Correct Answer: B. Reasonable grounds based on articulable facts to believe
