One paper considers the jurisdiction over Federal aras within Louisiana. Statutes and court cases are cited, and a list of federally owned properties is included. Another paper discusses wiretapping and the right to privacy. The fourth amendment is interpreted, and a history of wiretapping cases is presented. The third paper focuses on applications for search warrants. Relevant statutes, constitutional amendments, and court cases are discussed, and a search and seizure checklist is included in an appendix. Also, the doctrine of entrapment as a defense in criminal prosecutions and its applications to police investigations are discussed. Advice for police officers is provided, and statutes and court cases are discussed. In another paper, arrests and their ramifications are considered, with attention to the definition of an arrest, the circumstances under which a Louisiana police officer may arrest a suspect, the use of information from informants in determining probable cause, powers of detention, the use of force, obtaining assistance, and police activities following an arrest. Another paper focuses on the search and seizure of automobiles, with court cases serving as a basis for considerations of how the search and seizure laws for automobiles differ from those for buildings. Also discussed are automobile searches with and without warrants, searches incidental to arrest, in-clear-view situations, and suspect consent. The sixth amendment and relevant court cases are examined in a discussion of the right to counsel. The final paper discusses selfincrimination, confessions, and the Miranda case. Police strategies for gaining confessions are examined in view of court case outcomes, and rules which the police should observe in questioning suspects are presented. An appendix contains the text for the simplified short form of warning suspects of their rights and for a suspect consent-to-questioning form. Footnotes are included.
