Probable cause is a standard that supports which action?

• A. A mere hunch
• B. A standard that supports an arrest
• C. A requirement for a full search warrant
• D. A standard for temporary detention only

Answer: (B)

Probable cause is the level of justification police need to take a significant action in an investigation. It requires enough facts and circumstances to lead a reasonable person to believe a crime has been committed and that the person involved is connected to it. This standard is more than a mere hunch, but not as high as proof beyond a reasonable doubt. The action most directly supported by probable cause is making an arrest—police can seize and take someone into custody when probable cause is present. A mere hunch is not enough, and temporary detentions require only reasonable suspicion, which is a lower standard. While probable cause is also the standard for obtaining a search warrant, the option that best fits the described use is arrest.
