Which of the following is NOT a characteristic that may indicate a suspicious letter or package?

• A. Rigid or bulky
• B. Oily stains
• C. Postal stamp
• D. Restrictive markings

Answer: (C)

A postal stamp is a common feature of legitimate mail and does not inherently indicate suspiciousness. It serves as proof of payment for postage and signifies that the item was sent through standard mailing channels. In contrast, characteristics such as being rigid or bulky, having oily stains, or showing restrictive markings can be indicators of suspicious items. Rigid and bulky packages may suggest unusual contents or tampering, oily stains can point to hazardous materials, and restrictive markings may imply the item is intended for specific individuals or purposes, raising further concerns. Understanding these distinctions helps individuals identify potentially dangerous materials effectively.
