Brant v. Wisconsin

How later courts describe this case

• "proof that no first sale had occurred was not required because the government established that the tapes were pirated"
• “It would be unsound to invoke the exclusionary rule on the assumption that officers of one federal agency have such a strong motivating interest in all federal law enforcement concerns that broad application of the rule will achieve significant marginal deterrence”
• court declined to extend exclusionary rule to civil proceedings
• extending Janis holding to case involving federal agents
