The Disguised Minister

A wise minister, concerned about his country's true state, decided to experience life as an ordinary citizen. He disguised himself as a common civilian and ventured out alone, moving through bustling streets and quiet alleys. No one recognized him. However, his unusual solitary movements caught the attention of local police, who, mistaking him for a suspicious character, possibly a terrorist, promptly arrested him.

At the station, he was asked for his identity, which he initially denied to observe their procedures. The officers, growing impatient, interrogated him cruelly and threatened him with prolonged imprisonment. Seeing the extent of their prejudice, the minister finally revealed his true identity. The shocked police officers immediately apologized profusely. The minister, instead of punishing them, advised them to conduct careful investigations and never prejudge anyone based on appearances, ensuring no trouble for innocent people.

Moral: It is crucial to investigate thoroughly and not judge people based on their outward appearance or initial suspicions.
