Courts should determine whether an evidence-seizing officer's conduct was constitutional before determining, under the new regulation-conscious good faith analysis, whether suppression is the proper remedy. Given the Supreme Court's current view of the source and purpose of the exclusionary rule, the adoption of a broad good faith exception seems likely. Several courts have already adopted some form of a good faith exception. The heretofore absent incentive for the development of regulations that deter police from engaging in unconstitutional conduct can be provided by a properly structured good faith exception, one that rewards police departments that promulgate comprehensive fourth amendment regulation. A total of 277 case notes are provided. (Author summary modified)
