A reporter for the Chicago Sun in the United States pretended to be a businessman and opened a bar; in the bar they used a hidden camera to film local officials taking payoffs to allow the bar to stay open. The reporter later was nominated for a Pulitzer Prize for the series of reports he wrote. However, he did not win the prize because his method was not considered open and above-board enough.
美國「芝加哥太陽時報」曾由記者喬裝商人開酒吧，暗中用隱藏攝影機及錄音機蒐集官員貪汙證據，後據此寫成系列報導而獲提名普立茲獎，但決選時評審仍以手段不夠光明正大而未給獎。
