In the case of United States v. Halselth, 1951, the Supreme Court examined whether a federal statute that made it illegal to knowingly transport in interstate or foreign commerce any goods obtained by theft could be applied when the defendant had stolen money and used it to purchase airplane tickets. The defendant argued that he did not steal the actual plane tickets but rather purchased them with stolen funds; therefore, he should not be charged under this particular law. However, the court disagreed with his argument and held that using stolen money to buy goods which are then transported across state lines falls within the purview of this law. This decision expanded interpretation of what constitutes "goods" under such laws - including items bought with stolen money - thereby broadening its scope for future cases.

The dissenting opinion in the United States v. Halselth case argued that the majority's decision to uphold a conviction based on evidence obtained through an illegal search and seizure was contrary to Fourth Amendment protections against such actions. The dissent contended that allowing illegally obtained evidence to be used in court would encourage law enforcement officers to disregard citizens' constitutional rights, as there would be no consequences for their misconduct. It further suggested that this could lead to a slippery slope where other constitutional rights might also be violated without repercussion. The dissenting justices believed it was essential for courts not only protect individuals from unconstitutional searches but also ensure those who violate these protections are held accountable, thereby deterring future violations of citizens' rights.
