David D. Cole argued that the changes to the law were unnecessary, and accused the proponents of the USA PATRIOT Act of "equally guilty of propagating competing myths in this debate, nowhere more so than with respect to Section 218 and the "wall." He agrees that the wall was not required by FISA, and maintains that section 218 was not sufficient to reduce barriers between information sharing amongst agencies – this, he says, was and remains a bureaucratic issue and not a statutory one. He blames the CIA not trusting the FBI, and believes that pre-Patriot Act FISA was not the cause of problems of communications between the two agencies. Cole's argument is that the primary purpose test applied to acquiring foreign intelligence information when undertaking surveillance was "simply sought to reduce the risk that FISA, which permits searches on less than criminal probable cause, would become an end run around the constitutional requirement of criminal probable cause for searches conducted for criminal law purposes" and that although a secondary criminal purpose may later arise, the agency firstly must primarily gain the order to gain foreign intelligence information. He also dismissed the claims that before section 218 was enacted possible terrorist prosecution was not possible, citing the prosecution of Sami Al-Arian by the U.S. DOJ, which used FISA wiretaps undertaken before the Patriot Act was enacted, which fell under the pre-Patriot FISA law. He also attacks suggestions that when an investigation turned from foreign intelligence to a primarily criminal investigation then a wiretap would need to be taken down, instead positing that once it became criminal "government agents would simply have to satisfy the standards applicable to criminal investigations – namely, by showing that they had probable cause that the tap would reveal evidence of criminal conduct... [and the tap or the search would then continue".
