One of the recurring instances of this in the strip would consist of a guilty criminal who had been injured (either in the course of committing a crime or while attempting to evade capture) complaining that their constitutional rights had been violated.
While this theme was used as early as during the Boris Arson storyline, it became more prominent in Gould's later years.

Gould was criticized for letting his social commentary become excessive during the 1960s and 1970s. A repeated scenario in the strip would involve Tracy arresting a guilty criminal and then be forced to release the criminal, due to evidence being deemed insufficient and/or other legal technicalities. Tracy and his comrades would then be shown grumbling at how they were restricted in the ability to do their jobs.
