This is warrantless mass-surveillance, and done overtly. The US is still a democracy, and people should push back, and demand that their elected representatives block it. Justice Douglas, in his dissenting opinion on the 1974 California Bankers Association v Shultz case that upheld the constitutionality of the Bank Secrecy Act, provided an excellent argument against warrantless mass-surveillance and the doctrines, like Total Information Awareness, that promote it: It is estimated that a minimum of 20 billion checks - and perhaps 30 billion - will have to be photocopied and that the weight of these little pieces of paper will approximate 166 million pounds a year. 6 It would be highly useful to governmental espionage to have like reports from all our bookstores, all our hardware [416 U.S. 21, 85] and retail stores, all our drugstores. These records too might be "useful" in criminal investigations. One's reading habits furnish telltale clues to those who are bent on bending us to one point of view. What one buys at the hardware and retail stores may furnish clues to potential uses of wires, soap powders, and the like used by criminals. A mandatory recording of all telephone conversations would be better than the recording of checks under the Bank Secrecy Act, if Big Brother is to have his way. The records of checks - now available to the investigators - are highly useful. In a sense a person is defined by the checks he writes. By examining them the agents get to know his doctors, lawyers, creditors, political allies, social connections, religious affiliation, educational interests, the papers and magazines he reads, and so on ad infinitum. These are all tied to one's social security number; and now that we have the data banks, these other items will enrich that storehouse and make it possible for a bureaucrat - by pushing one button - to get in an instant the names of the 190 million Americans who are subversives or potential and likely candidates. It is, I submit, sheer nonsense to agree with the Secretary that all bank records of every citizen "have a high degree of usefulness in criminal, tax, or regulatory investigations or proceedings." That is unadulterated nonsense unless we are to assume that every citizen is a crook, an assumption I cannot make. Since the banking transactions of an individual give a fairly accurate account of his religion, ideology, opinions, and interests, a regulation impounding them and making them automatically available to all federal investigative agencies is a sledge-hammer approach to a problem that only a delicate scalpel can manage. Where fundamental personal rights are involved - as is true when as here the [416 U.S. 21, 86] Government gets large access to one's beliefs, ideas, politics, religion, cultural concerns, and the like - the Act should be "narrowly drawn" (Cantwell v. Connecticut, 310 U.S. 296, 307 ) to meet the precise evil. 7 Bank accounts at times harbor criminal plans. But we only rush with the crowd when we vent on our banks and their customers the devastating and leveling requirements of the present Act. I am not yet ready to agree that America is so possessed with evil that we must level all constitutional barriers to give our civil authorities the tools to catch criminals. Also worth noting that the threshold for reporting transactions when the BSA was passed, of $10,000, was worth $55,490 after adjusting for inflation. Now Treasury wants to decrease it to $600, which is a 92X decrease from the original threshold. If you factor in the 41% increase in real median income since 1974, the threshold the Treasury is pushing for would be 130X smaller, as a share of median income, than it was when the BSA was enacted. The BSA fell down the the slippery slope to total mass-surveillance.
