Answer :
Final answer:
For a valid warrantless arrest, police need to establish probable cause, which is a higher standard than reasonable suspicion. Reasonable suspicion allows for stops and frisks but does not suffice for full arrests. Therefore, police cannot rely on mere hunches or intuition for warrantless arrests.
Explanation:
Understanding Warrantless Arrests
To constitute a valid warrantless arrest, police need to have probable cause. Probable cause is the standard that law enforcement must meet to justify an arrest or search without a warrant, and it is based on the totality of the circumstances that would lead a reasonable person to believe that a crime has been committed or that evidence of a crime is present. This is distinct from reasonable suspicion, which is a lower standard, typically used for brief stops and frisks as established in the Supreme Court case Terry v. Ohio (1968).
Key Points
- Probable cause is necessary for warrantless arrests, not mere hunches or intuition.
- Reasonable suspicion is sufficient for stops and frisks, but does not apply to full arrests.
- In certain exigent circumstances, police can act without a warrant if they believe evidence may be destroyed.
