Criminal Procedure Flashcards
Constitutional amendments and associated crim pro rights
4th Amendment - prohibition against unreasonable search and seizure; 5th Amendment - Miranda/compulsory self incrimination and double jeopardy; 6th Amendment - right to speedy trial, trial by jury, confront witnesses, assistance of counsel; 8th Amendment - death penalty and prisoner rights
Exclusionary rule and limitations
Procedure whereby someone who has been the victim of an illegal search or a coerced confession can have the product of that illegal seach/coerced statement excluded from any subsequent criminal prosection. EXCEPTION: grand jury proceedings, civil proceedings, parol revocation proceedings and does NOT apply to use of excluded evidence for impeachment (although can only be used to impeach defendant not other witnesses). Also, violations of knock and announce rule don’t get this protection
Fruit of the poisonous tree doctrine
excludes illegally seized evidence but also excludes all evidence obtained or derived from police illegality. DOES NOT apply to Miranda violations unless in bad faith
Three ways to break the chain between original, unlawful police action and a supposedly derived piece of evidence
3 IN’s (as in they are “in”) - 1) show independent source; 2) inevitable discovery; 3) intervening acts of free will on the part of the defendant
Test for overturning a conviction on appeal for admitting improperly obtained evidence
Harmless error (i.e., conviction will be upheld if the conviction would have resulted despite the improper evidence)
Standard for which to base an arrest
probable cause
Are warrants required to arrest someone in a public place?
Generally, no
Are warrants required to arrest someone in his home?
Yes, if it’s a non-emergency situation
Station house detention doctrine
police need probable cause to arrest you and compel you to come into the police station for either fingerprinting or interrogation (note: don’t need this if they merely ask)
Investigatory detentions/Terry stops defined
Police have authority to briefly detain a person even if they lack probable cause of arrest. In order to make such a stop they must have 1) reasonable suspicion supported by 2) articulable fact of criminal activity. Measured by totality of circumstances
Automobile stops (special Terry stop)
Cops may stop a car if they have at least a reasonable suspicion that the law has been violated. Doesn’t matter if they have ulterior motive. Exception: check point roadblocks - must be neutrally applied (e.g., DUI checks, border crossing)
Steps to evaluate search and seizure problem
1) government conduct? 2) reasonable expectation of privacy? (e.g., standing) 3) did police have a valid search warrant? 4) if warrant not valid, does an officer’s good faith defense save the defective search warrant? 5) If warrant invalid and can’t be save by good faith, or if no warrant at all, does the situation fall under the exceptions to the warrant requirement?
What constitutes government conduct?
1) publicly paid police - on or off duty; 2) private individual acting at direction of public police; 3) privately paid police actions do NOT constitute gov’t conduct UNLESS deputized with power to arrest you
Automatic categories of standing (reasonable expectation of privacy)
1) you own the premises searched; 2) you live on premises searched, whether you have ownership interest or not; 3) you are an overnight guest on the property
“Sometimes” category of standing
1) you own the (non-real) property seized (only have standing if you have reasonable expectation of privacy in the item or area searched)
No standing categories
1) sound of your voice; 2) style of your handwriting; 3) paint on the outside of the car; 4) account records held by a bank; 5) monitoring the location of your car on public street or in your driveway; 6) anything seen across the open fields (even if fenced in); 7) anything that can be seen from flying over in the public airspace; 8) the odors emanating from your luggage or car; 9) your garbage set out on the curb for collection
Two core requirements for facially valid search warrant
1) probable cause (a fair probability that contraband or evidence of a crime will be found in the area searched) and 2) particularity (warrant must state with particularity the place to be searched and the property to be seized)
Ability of an officer to base his affidavit/probable cause for warrant on informant
Sufficiency determined by totality of circumstances; an informant’s credibility and basis of knowledge relevant factors; valid warrant can only be based in part on tip from informant; informant can be anonymous
When is no knock entry in execution of a search warrant permitted?
if knocking an announcing would be dangerous, futile, or inhibit the investigation (e.g., destruction of evidence)
General rule of officer’s good faith defense to a defective warrant
officer’s good faith reliance on a search warrant overcomes defects with the probable cause or particularity requirements
