"The Control Yuan will begin an investigation on NPA director-general Wang Cho-chiun, NSB chief Tsai Tsao-ming and sec-gen Su Chi to see if they've committed administrative wrongdoing when handling demonstrations during Chen Yunlin's visit. The investigation may run from 3 months to 6 months. If they're found guilty, they'll be impeached. Huang Huang-hsiung (黃煌雄) will be in charge of the investigation. He's a former legislator affiliated with the DPP, who seems to be quite insisting on "DPP's founding principles" (and thus has been keeping a distance with the Chen Shui-bian administration towards the end of Chen's term)." -- Loa Iok-sin, Taipei Times reporter.
