Is television realistic?
Most people have knowledge of criminal investigations acquired from TV shows. Some popular ones are, CSI: Crime Scene Investigation, Law and Order, NCIS, White Collar, Psych, Covert Affairs, Castle, Rizzoli & Isles and many more. These shows are only entertaining because they are nothing like reality, if they were realistic, people wouldn't watch them.
Back to Basics:
Criminal investigation is a process in which the objective is to unravel the information about a committed crime. Investigators are on a mission to discover the answers to questions like who, what, where, when, why, and how. Once they have information on a few of this questions, they can connect the dots and figure out the rest of the puzzle, however, the puzzle does not get solved as quickly as TV shows portray. In reality, solving a case could take several weeks, months, and even years.
Qualifications:
Like any other career, criminal investigation requires degrees and extensive studies. Qualifications vary from agency to agency, but most agencies prefer to have a college degree in law enforcement, criminal justice or other related field, to have performed one year of patrol duty. In order to work in a federal department, it is a necessity to have a bachelor's degree in a field related to law enforcement. In addition, the job of a criminal investigator demands good interviewing and communication skills, patience, trust, honestly, logical thinking and reasoning, ability to be perceptive to certain reactions, problem solving/decision making skills, and good physical and mental health.
Yes, it is definitely not a mainstream job and yes it's not common for women to do such jobs, but what's the harm in doing something different than everybody else. Just another potential career among a wide range of others.
