5. Obtaining evidence and information by means of voluntary conversations • Most persons will engage in voluntary conversations, however, with law enforcement officers. • If at some point they wish to discontinue the conversation, they may do so.

6. “Free to leave” test • The test used by courts to determine whether such situations are voluntary or not is the free to leave test , which is defined by the U.S. Supreme Court as follows: • A person has been “seized” within the meaning of the Fourth Amendment only if in view of all the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave.

7. Terry Stops • The amount of evidence known as reasonable suspicion is needed to authorize an investigative detention, or Terry Stop. • Reasonable suspicion is less than probable cause • Terry v Ohio (1968)

9. Searches that can be justified during an investigative detention • Consent to search would have to be voluntarily and clearly given. Consent searches would be limited to the area or object consented to the searched. • Protective search can be made if an officer who has made a valid investigative stop has reasonable suspicion to believe that the suspect “ may be armed and presently dangerous.

14. Evidence obtained during inventory searches • Inventory searches: are not “searches” for incriminating evidence. • They are a common and sensible police procedure to determine what the law enforcement agency is responsible.

15. Searches of Private Premises • Arrest Warrants vs. Search Warrants • In Arrest Warrants, you’re looking for a PERSON • In Search Warrants, you’re looking for EVIDENCE

20. Vehicle stops • Police need at least “reasonable suspicion” to make a stop • Most are temporary, brief and public • It does “curtail one’s freedom of movement” • Drivers and Occupants may be questioned • All occupants may be ordered out of the vehicle

21. Evidence during traffic stops • Plain-view doctrine may allow officers to “seize” evidence that they can “see” while in “plain view.” • This can give probable cause to search the entire vehicle! • Consent can be also used to ok a search • Police have an “Automobile Exception” to search vehicles that is unique…

22. The Automobile Exception • Carroll v U.S. (1925) • Established the “Carroll Rule,” or the PROBABLE CAUSE rule in dealing with vehicles. • Essentially, because vehicles can be moved easily, and evidence destroyed, etc., the police can search the vehicle where it is, as long as they can articulate PROBABLE CAUSE for the search. • A warrant is not needed, nor is consent, as long as PC is present

23. Key Cases • Carroll v. U.S. 45 S. Ct. 280 (1925) • U.S. v. Ross, 102. S. Ct. 2157 (1982) • Ross extended searches to the ENTIRE vehicle, including the trunk as well as closed containers, AS LONG AS THE POLICE HAD A LEGAL REASON TO STOP THE VEHICLE AND PROBABLE CAUSE TO SEARCH!
