What indicates you might be suspicious of a delivered package?

The presence of protruding wires in a delivered package is a significant indicator of potential danger that warrants suspicion. Wires could suggest that the package may contain electronic components or devices that could pose a risk. In emergency response protocols, the sight of exposed wires often raises alarms about the possibility of explosives or other hazardous materials, making it crucial to exercise caution in such situations.

Other factors, while they may also raise concerns, tend to be less definitive on their own. An unusual smell or an unexpected weight might be noteworthy as well, but they do not carry the immediate implication of threat that protruding wires do. Similarly, wrapping in plastic could merely be a packaging choice without indicating danger unless accompanied by other suspicious signs. Therefore, the indicative nature of protruding wires makes this the most concerning warning sign in the context of possible package threats.
