What could be a reason the characters chose the mall as their cover story?

Choosing a mall as their cover story is effective primarily because it is a public and popular location. Malls generally attract large crowds, making it easier for characters to blend in and avoid drawing attention to themselves. Being in a bustling environment provides a sense of normalcy and can deflect suspicion, as it's typical for people to visit malls for various reasons. This setting allows them to navigate their activities discreetly amidst a diverse group of shoppers.

While enjoying shopping, wanting to see friends, or having an event to attend could provide individual motivations, they do not fully capture the strategic advantage of using a mall as a cover story. The mall's public nature is what truly enhances its effectiveness as a plausible alibi or cover, creating an environment where the characters can carry out their intentions without alarming others.
