The latest controversy to hit the government was sparked by comments Centers for Disease Control (CDC) Deputy Director-General Shih Wen-yi (施文儀) posted on his Facebook page concerning the US’ visa-waiver policy and a decision to extend the National Health Insurance program to Chinese students. The Executive Yuan is to investigate whether Shih violated the Civil Servants Work Act (公務員服務法). The government is being rather selective in what it decides to investigate: Is it thinking of hoisting Shih’s head on a spike outside the city gates as a warning to others? This raises questions over freedom of expression.
