This political cartoon depicts Tweed as being immune from the justice system, but lurking behind him is the shadow of Justice, waiting, plotting. The criminal actions of William M. Tweed (Boss Tweed) and Tammany Hall, the Democratic political machine in New York City, had finally come into the public eye. Millions had been stolen from tax payers. Even after his removal, Tweed's wealth and power seemed to safeguard him from prosecution. Any normal man would have been dealt with swiftly, but Tweed walked free until 1873. His first trial was even thrown out, leading the politician to boast that he would never be imprisoned. He then went off to enjoy vacation. Lawyers used the next several months to rework their case and a retrial later in the year landed them with a guilty verdict.
