WHAT'S THE DIFFERENCE BETWEEN A COP AND KEVIN MAHER? KEVIN DOESN'T HAVE A BADGE. AND HE DOESN'T PLAY BY THE RULES. Cop Without a Badge tracks confidential informant Kevin Maher as he helps the NYPD, the FBI, and many other law enforcement agencies solve cases that range from robbery to extortion to homicide. In the process, Kevin becomes the highest paid CI the DEA ever had. But Kevin's motives are more complicated than simply money. Having been arrested for Grand Theft Auto at the age of sixteen, his felony conviction prevents him from being what he always wanted to be: a police officer. So now he's out to prove to himself he truly is what he could've been.
