Private investigation doesn't mean that an individual should be a part of the CIA or FBI. Rather, the individual private investigator works alone most of the time using his skills, experience, and network of contacts to obtain what he needs for the case.

A private investigation involves great risk on the safety of the investigator since one doesn't have any cover in case something wrong happens. Often resigned or retired policemen and servicemen take the job of private investigators. They know what it takes to work on such dangerous grounds.

Information is Key

Obtaining information is crucial to the success of a private investigation. Without any gathered information, a private investigator may be out of business because he cannot solve the case at hand.

There are several avenues on how information is gathered during private investigation:

• Research – private investigators may need to browse through old records to get a proper perspective of a specific case. Research is time consuming and can be taxing. Databases of past records provide a great deal of information which may be useful to answer all the questions involve in the investigation.

• Interviews- this maybe the most important aspect of private investigation. Mysteries are solved by obtaining answers using the art and science of questioning people. Using the right language is very important to make someone give very important information.

• Forensics – this involves looking at all clues which may lead to a breakthrough in a case. All finger prints, paper trail, shoe prints, and a lot of other data that are pertinent to the investigation. It also involves proper handling of possible evidences without contaminating them.

• Surveillance – a private investigator closely monitors the subject to generate information that maybe useful for the case at hand.

Protection While on the Job

One may encounter some resistance when doing surveillance jobs. People or organizations may not appreciate the investigation that intrudes their privacy and may be a violent threat to the private investigator.

A lot of private investigators have sacrificed their lives while on the job. Knowing this, private investigators make it a point that they have some know how or weapons to protect themselves:

• Martial Arts - with this PI's can neutralize opponents using proper striking techniques. Some famous schools of self defense are karate, judo, and taekwo ndo.

• Yawara-bo - this weapon is connected with the jiu-jitsu techniques. It is a tool shaped like a pen or a small flashlight. It can be hidden anywhere to give an impression that one is not armed. It is used to apply pressure on some parts of an attacker to immobilize him.

• Pepper spray- this comes handy for PI's to gain an upper hand in case of an attack. It will be helpful if a PI has not mastered self defense yet.

• Stun Gun- this delivers electric shock through the muscles of an attacker. The high voltage makes the muscle immovable for a certain period allowing a PI to take advantage or run away from the situation.
