Which of the following is a key difference between surveillance and countersurveillance?

The correct answer highlights that surveillance is primarily concerned with gathering information about individuals, activities, or locations, often with the goal of detecting potential threats or criminal behavior. This process involves observation and intelligence collection to understand patterns and behaviors that may indicate unlawful activities.

On the other hand, countersurveillance is about avoiding detection and concealing one's actions or movements from those who might be conducting surveillance. This can involve techniques designed to thwart surveillance efforts, such as changing one’s route, using disguises, or employing countermeasures to confuse or mislead the surveillant.

The focus of surveillance on data collection marks a clear distinction from countersurveillance, which is defensive and proactive in evading the watchful eyes of those who are observing or monitoring for suspicious activities or potential threats. This understanding of the operative intents and methodologies of both surveillance and countersurveillance is crucial for law enforcement professionals engaged in security and protective operations.
