Terry v. Ohio

Brower v. Inyo County

Seizure occurs when government termination of a person's movement is effected through means intentionally applied.

California v. Hodari

In order for a seizure to have occurred there must either be some application of physical force, even if extremely slight, or a show of authority to which the subject yields.

Mapp v. Ohio: Supreme court decision set the judicially established rule that prohibits the use of evidence obtained in violation of the 4th amendment in court.

Fruit of the Poisonous Tree

US vs. Leon says that the exclusionary rule should be modified so as not to bar the admission of evidence seized in reasonable, good-faith reliance on a search warrant that was subsequently held to be defective. (Upheld in Herring vs. US)

"plain view" doctrine

The rule, from the Supreme Court decision in Harris v. U.S, that anything a police officer sees in plain view, when that officer has the right to be where he or she is, is not the product of a search and is therefore admissible as evidence.

Miranda v. Arizona

If a subject is in custody and interrogation is going to take place, Miranda Warning/Rights are required to be recited.

The right of a person to complain in court about hte lawfulness of a police action (arrest, detention, search, frisk)

Montejo v. Louisiana

No reason to distinguish, for the purposes of a suspect waiving their rights, a represented individual from an unrepresented one (no attorney). For each a Miranda warning adequately inform the individual of their right to counsel.

Binding Authority

Ramirez v. Texas

May constitute custody: "physically derived of freedom of action in any significant way" or "When a law-enforcement officer tells the subject he cannot leave"

US v. Mendenhall

to determine whether an arrest has taken place, a court will apply an objective standard, focusing on the reasonable impression conveyed to the person subjected to the apprehension and detention. In this respect, the inquiry is whether, in the view of all the circumstances surrounding the encounter a reasonable person would have believed that he was not free to leave.

Rhodes v. Texas

Handcuffing of suspect during detention for safety was reasonable and justified and did not convert to arrest.

Stansbury v. CA

traffic stop doesn't constitute custody for Miranda purposes. However noncustodial custody can turn into custodial custody because the situation escalates. Consider Intent, Authority, Seize and detain, understanding of the individual being arrested. The mere denial of intent to arrest by the officer will usually be insufficient.

Florida v. Royer

Consensual Encounters okay -- says LEOs don't violate the 4th amendment by merely approaching an individual on the street or in another public place by asking them if they are willing to answer some questions. Must be voluntary.

Crain v. Texas

Flight is not necessarily indicative of ongoing criminal activity, however a defendants unprovoked flight from officers in areas of heavy narcotics trafficking supports reasonable suspicion that may be involved in criminal activity and justifies a stop.

Guzman v. Texas

P.C. for arrest deals with probabilities; it requires more than mere suspicion, but far less evidence than that needed to support conviction or even that needed to support finding by preponderance of evidence. Totality of the circumstances was cited in court's decision.

Aguilar v. Texas (and Illinois v. Gates)

Established a two prong test for search warrants that require a: 1. A credible source, 2. A reliable base of knowledge. This decision was overturned with Illinois v. Gates which held that even though an anonymous tip might not be a credible source, that when detailed facts of innocent activities are corroborated, then P.C. for a warrant may exist.

Definition: Probable Cause

A reasonable ground to suspect that a person has committed or is committing a crime or that a place contains specific items connected with a crime. At the moment of arrest probable cause ceases to build.

Affirmed Terry v. Ohio Detention and Frisk provisions (at CCA state level).

Armstrong v. Texas

Illegal stop and arrest. Consent to search given after arrest and the court concluded that under these circumstances the evidence was seized through exploitation of the illegal stop rather than by means sufficient to remove the primary taint.

Adams v. Williams

Reasonable suspicion of r a stop and frisk need not be based only upon an officer's personal observations but may also be based on information supplied by another person.

Ohio v. Robinette

An investigative detention must be temp. and last no longer that is necessary to effect the purpose of the stop unless additional suspicious activity is found o justify the prolonged detention.

US v. Arvizu

In making reasonable-suspicion determinations, reviewing courts must look at the "totality of the circumstances" of each case to see whether the detaining officer has a "particularized and objective basis" for suspecting legal wrongdoing. This process allows officers to draw on their own experiences and specialized training to make inferences from and deductions about the cumulative information available.

Hurtado v. Texas

Originally stopped because tag came back with possible warrant for driver. It wasn't the driver, but court said stop was good and subsequent cocaine discovery was prosecuted.

3 Prong Test from Hoag v. State

3. Some indication the suspicious activity is related to a specific offense.
