"From the early foundation of America to where it stands today, Opions throughout history: Law enforcement in America looks at how American attitudes on police and the law have been shaped and have changed, and at ideas on how American policing should evolve to reflect the changing cultural landscape in America. This wide-ranging text covers: the early beginnings of American law enforcement and how it evolved starting from colonial law and slave patrols; the formation of the Miranda warning; citizen surveillance in the new police state; recent police protests including the Black Lives Matter movement. Each chapter discusses both primary and secondary documents such as newspaper and magazine articles, speeches, court decisions, and other legislation. Accompanied by expert commentary and analysis, this volume will guide the reader through the process of how each document affected the changing attitudes on this important issue of public interest." --
