Protective Surveillance

CIS investigators assist clients throughout Florida in monitoring potentially-dangerous persons and providing early warning of impending violence.

Following hostile terminations, there is often a dangerous and uncertain period as the fired employee processes the situation outside the scope of the company’s observation and influence. And without effective provisions for monitoring the behavior and mental state of the discharged employee, there is often little the employer can do at this stage to anticipate or prevent potential violence.

Many organizations respond to this situation by temporarily hiring off-duty police or armed security officers. Although heightened security presence may be useful in the short run, eventually a decision will be required to indefinitely maintain the new security posture or return to normal. When this question arises, organizations without updated threat information face a difficult decision.

As an alternative to raising the level of security, it is often more cost-effective to conduct a protective surveillance of the person of concern.

In protective surveillance operations, CIS investigators discreetly monitor the activities of potentially-dangerous individuals with a focus on behaviors indicating an improving or deteriorating threat situation, such as:

    • Evidence of social withdrawal, depression, or nihilism (e.g., depressive demeanor, alcohol or drug abuse, lack of personal hygiene, absence of social interaction, relationship problems, etc.).
    • Behaviors indicating planning or preparation for committing violence such as visiting gun stores or shooting ranges, casing employees or the workplace, etc.
    • Behaviors suggesting that the person of concern is coping with the situation and making an effort to regain employment.

In addition to collecting threat assessment information, protective surveillance operators provide a valuable security function. If at any point the subject is observed preparing for violence (e.g., loading weapons into a vehicle, wearing tactical gear, etc.) or driving in approach to the facility, CIS investigators can provide early warning to police and facility management, and if necessary, intervene as armed responders.
