Turning Point
Al Capone was arrested for tax evasion, because the government could not find enough evidence to send him to jail for his other illegal activies including bootlegging, murder, and racketeering. So Capone's type of conviction changed history by providing prosecutors with another mechanism to prosecute someone: tax evasion. For example, a person might not get prosecuted for actually selling drugs, because there may be not enough evidence of the actual sale of the drugs. by that person. But, the drug dealer might have accumulated so much money and lack a credible explanation of where or how he acquired the money. Further, just as in Al Capone's case, this hypothetical drug dealer would not have paid taxes on the drug money. Because he is does pay his taxes, he could get prosecuted for tax evasion.
