What is the difference between probable cause and reasonable suspicion in searches?

• A. Probable cause is a vague standard with no clear threshold.
• B. Reasonable suspicion and probable cause require the same level of evidence.
• C. Probable cause only applies to arrests, while reasonable suspicion only applies to seizures.
• D. Probable cause requires a higher likelihood of evidence; reasonable suspicion is a lower threshold based on specific facts and rational inferences leading to a limited intrusion.

Answer: (D)

The key idea is understanding two different confidence levels the government must have before acting. Reasonable suspicion is a relatively low threshold: it requires specific, articulable facts and rational inferences from those facts that would lead a reasonable person to suspect that criminal activity is afoot. This level justifies a brief, limited intrusion such as a stop or investigative detention, not a full search. Probable cause is a higher standard. It requires a greater likelihood that evidence will be found or that a crime has been committed, based on the totality of the circumstances. This stronger showing is what justifies more invasive actions, like arrests or obtaining a search warrant, and it supports searches conducted with those warrants or under certain exceptions. So, the correct concept is that probable cause entails a higher likelihood of evidence and supports more substantial actions, while reasonable suspicion is a lower threshold that allows only limited intrusions.
