Members of the tangwai movement (an unofficial group that opposed the ruling party during the period of martial law, when opposition parties were outlawed) showed reporters the bloodstained T-shirt of a protester whom they claimed had been beaten by the police. The authorities were accused of police brutality, and a huge photograph of the bloodied man appeared in the newspapers, drawing the concern of human rights organizations abroad.
當時，黨外人士拉著一個被打得頭破血流、T 恤上沾滿大片鮮血的民眾指控「警察打人」，斗大的照片登在報紙上，引起關心人權的國際人士注意。
