If California Senate Bill SCR 54 is enacted, as seems likely, the California Law Revision Commission will be tasked with modernizing California statutory law on law enforcement access to customer records of cell phone providers, internet service providers, social media companies, and other mobile and internet-based communication providers. The Commission would like us to prepare a thorough and balanced background study of the relevant legal and policy concerns, including civil liberties, public safety, and the scope of federal preemption in the area, with an emphasis on new and emerging communication services. This is likely to be a high profile project, with close attention from the Legislature and many interest groups. nThis project involves complex issues under the Fourth Amendment and such statutory structures as the Electronic Communications Privacy Act. Completion of the course in Criminal Investigation is a prerequisite, with exceptions only for those with demonstrable alternative background in Fourth Amendment law.nElements used in grading: As agreed to by instructor.
