Scott Shimick, SUNY, Geneseo, is publishing Heisenberg's Uncertainty: An Analysis of Criminal Tax Pretextual Prosecutions in the Context of Breaking Bad's Notorious Anti-Hero, in the Tulsa Law Review. Here is the abstract. 

Commentators have roundly criticized pretextual prosecutions, such as prosecuting Al Capone for tax evasion rather than bootlegging, arguing that the government should minimize the use of pretextual prosecutions. However, pretextual prosecutions serve as a valuable tool for law enforcement.
In Breaking Bad, Walter White becomes a violent criminal who produces and sells narcotics. Throughout the series, he is very careful to conceal or destroy any evidence linking him to the violence and drug trafficking. However, as the bootleggers and gangsters of the Prohibition-era learned, the government holds the trump card, criminal tax prosecution. By charging drug traffickers with criminal tax fraud, the government can imprison dangerous criminals without having to prove beyond a reasonable doubt that the drug traffickers actually produced and sold narcotics. This article examines criminal tax fraud statutes and methods of proof, analyzing these statutes and methods in the context of whether Walter White should have fled from prosecution. Through this analysis, this article demonstrates the value of pretextual criminal tax fraud prosecutions.
