Fourth Amendment

Focuses on protection against unreasonable searches and seizures.
Key terms:
- Unreasonable Search: If deemed reasonable, no warrant is necessary.
- Warrant Requirements: Must particularly describe the place to be searched and the persons or things to be seized.
Determining Reasonableness:
- A primary aspect is to identify if a government actor is involved.

Scenario 1:
- Victoria breaks into Molly's house without police involvement and finds illegal items.
- Result: Evidence is not excluded as no government actor was involved.
Scenario 2:
- Victoria, believing Molly is dealing drugs, contacts the police. Police advise her she can enter, but they cannot without a warrant.
- Victoria enters, retrieves items, and at trial, her attorney seeks to exclude evidence.
- Outcome: Evidence is excluded because Victoria acted as a quasi-government actor, effectively functioning under police direction.

A hearing to investigate the circumstances of the search and to determine the truth regarding police authorization.
Goal: To establish if actions taken were in pursuit of legal authority or if misinformation was presented.

Katz v. United States (1967): Established the precedent that Fourth Amendment protects people, not places.
- Details:
- Katz, who placed bets over the phone, had his phone calls intercepted without a warrant.
- The impact: Shift in privacy law as it relates to eavesdropping and telecommunication.
Expectation of Privacy Test:
- Two-pronged test:
1. Objective Expectation: Society decides whether an activity deserves privacy.
2. Subjective Expectation: Individual actions that demonstrate a desire for privacy.

Example 1: Making a phone call from a booth; socially perceived as private.
Example 2: Someone dealing drugs with open curtains cannot claim privacy; actions contradict subjective expectations.
Crucial Distinction: Verbal conversations in public places (e.g. restaurants) generally lack a reasonable expectation of privacy.

Major historical context spans back to pre-revolutionary laws that forbid general warrants, ensuring specific and provable cause for intrusion.
Requirements for a Warrant:
1. Probable Cause: Must be supported by an affirmation or oath; if inadequate, cannot serve as grounds for a warrant.
2. Particularity: The warrant must specify precisely what will be searched or seized to prevent general searches.
3. Neutral Magistrate: Requires a detached judicial officer to issue warrants, protecting against bias.

Standard: An officer must show that under totality of circumstances, a reasonable person would believe a crime may be occurring.
- Basis for Belief: Officer’s observations, collective knowledge within the force, and informants.
- Credibility of Informants: Use of confidential informants versus anonymous sources, documentation of their reliability, and relevance to operational circumstances.

After items are seized, police must present all items to the court and keep them secured until required for trial.
Police are expected to knock and announce their presence unless a no-knock warrant is justified.

Certain situations do not require a warrant for searches:
- Terry v. Ohio: Establishes stop and frisk, where officers may detain suspects based on reasonable suspicion of crime occurring and an officer's assessment of potential danger. Not requiring probable cause.
Consent Searches: Must be voluntary, and only those with apparent authority may grant consent.

Good Faith Exception: If a warrant is executed in good faith, despite issues of bias or defects, evidence may still be admissible under the exclusionary rule.
Inevitable Discovery Rule: Evidence discovered constitutionally through independent means is admissible.
Public Safety Exception: Allows for immediate search responses when there are articulable concerns about immediate danger.

Ultimately, evidence obtained through unreasonable search is excluded, ensuring adherence to constitutional rights—an essential pillar in the legal system's checks and balances.
Continuous testing against practical scenarios enrich understanding and application of these constitutional protections.

Awareness and intricacies of the Fourth Amendment’s protections, warrant requirements, and exception rules are essential for effectively navigating legal environments and protecting personal rights.
