Problem: I need cases like Katz v. United States (1967) , additionally I need the basis of legal action, defense, issue, and relief saught with the following scenario:
Police saw a person buy chemicals that could be used to make illegal drugs, w/o a warrant they put a wiretap on the guys phone and found where the guys warehouse was where they were manufacturing.. they arrested the guy there. The attorneys defense wants to make a motion to exclude evidence seized as a result of the wiretap what case law discusses the unauthorized use of wiretaps.
