What specifically do the terms uniformed or plain-clothed mean?
The decision to have a uniformed guard or a plain clothes guard should simply be based on whether it is more important for you to deter people or to catch them in the act. Keeping people honest is often cheaper and much less time consuming than catching them in an act of dishonesty. In commercial situations uniformed guard can be very effective in deterring customers and employees in gross acts of dishonesty. Plain clothes guards, on the other hand, are essential for stopping shoplifters because they blend in and are discreet.
