Cops, Detectives, Agents, PI's and Consultants

Who says our protectors don't have problems too. some of these cops are worse than criminals (Graceland) (Chicago PD) (Gang Related) and some of them deal with forces we can't understand (supernatural)(Lost Girl) (Beauty and the Beast). but there are those that are in a league of there own (the mentalist) (castle) (psych) (the closer). and those with amazing intellect (elementary) (bones) (scorpion) the one thing they all agree on is people are capable of anything given motive and opportunity.
