This four-hour audio lecture on criminal law is useful for students who are about to take or are currently taking a course in Criminal Law and who want to use it for class review or exam preparation. But it is also useful for anyone, student or not, who would simply like to gain a more informed sense of just what American criminal law is all about. Coverage includes the traditional, foundational doctrines of criminal law like criminal intent and criminal act, discussing these concepts in dealing with crimes like homicide offenses, assault and sexual assault, theft and other property crimes. This lecture also focuses on traditional and modern defenses to criminal charges, like insanity, self defense, and the modern “Stand Your Ground” laws. But just as important as discussion of these crimes and defenses, the lecture also covers some of the most significant structural issues and skills that should be useful to you to figure out how criminal trials work, issues like distinguishing the roles of lawyers, judges, jurors and legislators, and skills like applying criminal statutes to particular cases and analyzing appellate decisions. Some useful tips on studying for and taking Criminal Law exams are included at the end.
