Which item is NOT typically an indicator of sex trafficking at a location?

The presence of art supplies would not typically be an indicator of sex trafficking at a location. While the other options generally suggest activity related to sexual exploitation or the facilitation of such activities—like cameras and cash indicating potential video recording or financial exchanges, printed advertisements suggesting solicitation, and pornographic materials indicating the promotion of sexual services—art supplies do not inherently imply any connection to sex trafficking. Art supplies might signify creative work or hobbies unrelated to illegal activities, making them less relevant in identifying signs of sex trafficking. This distinction highlights that trafficking indicators usually revolve around items directly associated with exploitation or commercial sex rather than benign materials.
