Which concept is allowed with reasonable grounds for crime belief?

• A. Reasonable Suspicion
• B. Detention Justification
• C. Photo Array
• D. Warrantless Arrest

Answer: (D)

Probable cause is the standard that allows a police officer to arrest someone without a warrant. It means there are enough facts and circumstances to lead a reasonable person to believe the suspect has committed a crime, not just a hunch. This higher bar distinguishes a full arrest from a mere investigative stop, which rests on reasonable suspicion and may justify brief detention but not an arrest. A photo array is a tool for identifying a suspect after detention or arrest, not a basis for making an arrest itself. Detention justification isn’t the same as probable cause for an arrest, so it doesn’t authorize a warrantless arrest on its own.
