This guide is a quick and handy reference for law enforcement officers on how the Constitution, as interpreted through various court decisions, influences their contact with the public. Murrell and Dwyer present a sound framework against which the practice of law enforcement may be measured. The book is not meant to be a complete list of "Do's and Don'ts," because various state laws and local regulations, as well as agency guidelines and procedures, may also have a bearing on the breadth of enforcement authority given to police officers. Therefore, where more restrictive guidelines are in place, the reader is cautioned to make a note of them.
