You become powerfully INFORMED. Being a private detective, gives you the ability to delve into other people's secrets. There are many different opportunities for private detectives to gain access to people's dirty laundry.
Legal investigators: Help verify facts in civil law suits, prepare criminal defenses, and serve legal documents. You get to say, "Your butt just got served." However, you should walk away quickly after saying this. Sometimes run.
Computer forensic investigators: Recover, analyze, and present evidence from computers that is then used for investigations. These computer geniuses can find that deleted email you wrote to your boss five years ago.
Financial investigators: These detectives are usually hired by business big wigs to create confidential financial profiles of companies and individuals that are part of a large transaction.
Corporate investigators: Help companies by conducting external and internal investigations. They bust people who are abusing expense accounts, expose drug use in the workplace, or investigate fraudulent billing practices.
Hotel detectives: Protect guests from theft. Not that exciting unless you work for the Beverly Hills Hotel.
