This class provides a comprehensive exploration of Fourth Amendment principles, focusing on search and seizure law and its application to both the public and individuals under supervision, such as probationers and parolees. The course begins with a foundational review of the Fourth Amendment’s text, court interpretations, and key concepts like the expectation of privacy, warrant requirements, and exceptions. Special attention is given to the diminished privacy rights of those on supervision, examining relevant case law (Griffin, Knights, Samson) and how supervisory needs influence search standards. The curriculum also covers third-party search issues, with an emphasis on co-habitant consent and the controlling rules established in Randolph v. Georgia. Additionally, participants review recent legislative updates, including amendments to California Penal Code sections that clarify who may conduct probation searches and restrict certain practices by immigration officers. Throughout the course, students engage in hands-on exercises and scenario-based problem solving to apply legal standards to realistic situations, preparing them to analyze search and seizure issues confidently in their professional roles.
