The Terrorist Finance Tracking Program was viewed by the Bush administration as another tool in the "Global War on Terrorism". The administration contends the program allows additional scrutiny that could prove instrumental in tracking transactions between terrorist cells. Some have raised concerns that this classified program might also be a violation of United States and European financial privacy laws, because individual search warrants to access financial data were not obtained in advance. In response to the claim that the program violates U.S. law, some have noted that the U.S. Supreme Court in "United States v. Miller" (1976) has ruled that there is not an expected right to privacy for financial transaction records held by third parties and that "the Fourth Amendment does not prohibit the obtaining of information revealed to a third party and conveyed by him to Government authorities, even if the information is revealed on the assumption that it will be used only for a limited purpose and the confidence placed in the third party will not be betrayed".
