"Walker and Hemmens do a brilliant job of writing about complex cases and law so that the average reader and layman can comprehend the text. Even as a 13 year veteran, I gained valuable knowledge from the dozens of examples provided so that I could be better prepared on the street when making split second decisions; this is especially the case when covering search and seizure law. Overall, I would consider this one of the best books on the topic of constitutional law and its application to law enforcement that I have read. I highly recommend it."Marcus Downey, Sergeant, Alexandria Police Department
