What is the best practice concerning an investigator's disguise during surveillance?

The best practice concerning an investigator's disguise during surveillance is to ensure that it blends in with the surroundings. This approach allows the investigator to go unnoticed while conducting their activities, which is essential for gathering accurate and reliable information. A disguise that fits into the environment helps to avoid detection by the subjects being observed, thereby increasing the chances of successful surveillance.

Essentially, the goal of a disguise in this context is to maintain a low profile, allowing the investigator to carry out their duties without drawing attention. For example, wearing casual clothing that fits the demographic and setting of the area being observed is much more effective than an extravagant or overly noticeable outfit, which could arouse suspicion. High-tech disguises, while intriguing, may not provide the same level of subtlety and could be more conspicuous. Lastly, suggesting that a disguise isn't necessary undermines the very purpose of effective surveillance practices, as a lack of appropriate attire could lead to detection and compromise the investigation.
