Joe Banister is the only IRS Criminal Investigation Division Special Agent ever to investigate allegations that the IRS fraudulently and illegally administers and enforces the federal income tax and report his investigation results to his IRS superiors.  Rather than address legitimate concerns raised by one of the agency’s own criminal investigators, Banister’s IRS superiors suspiciously refused to address IRS wrongdoing raised in his report and instead encouraged him to resign.  Observing that IRS management intended to cover up the deceit and illegal conduct alleged in his report and elsewhere, Banister had no choice but to resign from his position so that he could report his findings to the American public, in effect having to resign from his office in order to abide by his oath to support and defend the U.S. Constitution.  More detailed background information about Joe can be found here.
