If you choose to defend Vidar, it will be revealed that Gamdin entered the H.A.M. Hideout and pickpocketed several agents, including Vidar, until he was caught and thrown into jail. If Vidar is prosecuted, it will be revealed that Gamdin had bought all the items he was found with from various shops in Lumbridge to bring back to his family as souvenirs and that, when walking around some ruins, H.A.M. agents violently abducted Gamdin.
