Who should of been keeping watch on the wooden horse?

The wooden horse should have been closely monitored by the Trojans, particularly their guards and leaders, who were responsible for the safety of their city. Key figures like King Priam and his advisors should have been vigilant, as they were aware of the Greeks' cunning tactics. Additionally, the soldiers stationed at the gates should have been instructed to keep a watchful eye on the horse to prevent any surprise attacks. Ultimately, a lack of caution and foresight led to the downfall of Troy.
