The white boards in undercover agents usually referred to the intelligence personnel who were undercover in the enemy's interior. Their mission was to pass on information and assist the police in capturing the enemy. The undercover agents were not civilians but agents sent by the police or other law enforcement agencies. Their mission was to provide intelligence within the enemy and assist the police in capturing the enemy, but that did not mean that they were enemies because their mission was to assist the righteous law enforcement agencies in carrying out their missions. Therefore, the white boards of spies belonged to spies and not civilians.
