This weekend we worked an infidelity investigation where we were following a husband because his wife thought he was seeing another woman.  After 4-days of surveillance we reported no evidence that the husband saw another woman.

The wife was upset with the results because she still believed that her husband is cheating on her.  We reported our investigative finding and showed the wife video evidence of the husbands activates for the weekend.  She still was not satisfied. 

I feel that anytime you conduct an investigation you need to have clearly defined objectives.   If you have doubts as a spouse provide the investigator with as much information as you have and accept the results of the investigation.

Even if your company is not involved in classified activities, you may still be the target of espionage activities by foreign governments. 

There are a number of laws restricting the export of materials such as encryption software or advanced electronics. Foreign governments will seek other avenues to get access to these products. Any organization that handles restricted items should have a counter intelligence program in place. While this may sound farfetched, there are numerous examples of these operations. For instance, many model rocketry clubs have implemented criminal background checks on new members because terrorist organizations try to infiltrate them to obtain explosives. 

If you have strong evidence of espionage, particularly if criminal or foreign intelligence activities are suspected, then the police or the FBI would be the place to go. However in most cases, companies have no idea that this is happening. Implementing a counter intelligence office sweep is an important first step in discovering these activities.
