Walker is professor emeritus of criminal justice at the University of Nebraska at Omaha, has written 13 books on policing and civil liberties, and he served as a consultant to the Justice Department.
Writing in the Los Angeles Times, Walker says:
Scalia's opinion suggests that the results I highlighted have sufficiently removed the need for an exclusionary rule to act as a judicial-branch watchdog over the police. I have never said or even suggested such a thing. To the contrary, I have argued that the results reinforce the Supreme Court's continuing importance in defining constitutional protections for individual rights and requiring the appropriate remedies for violations, including the exclusion of evidence.
