Legislator Puma Shen's 'Fifth Column Monitoring' Proposal Met with Fierce Backlash and Accusations of New McCarthyism

Around June 8, 2024, newly inaugurated Democratic Progressive Party legislator Puma Shen triggered a major constitutional controversy in the Republic of China by proposing the monitoring of a potential 'fifth column.' During a media interview, Shen claimed that there were hundreds of thousands of individuals within the country who could potentially cooperate with mainland China to conduct cognitive warfare or subversion. He suggested that the government establish dynamic monitoring, notification, and reporting systems for 'high-risk groups,' including legislators, village chiefs, mainland spouses, and businessmen who travel to mainland China. The remarks immediately sparked widespread alarm and severe criticism. Opposition lawmakers and legal scholars slammed Shen, accusing him of attempting to revive a martial-law-era spy-catching apparatus and foster a climate of green terror, labeling him a 'new McCarthyist' and a 'thought police.' Critics argued that his surveillance proposals flagrantly violated the constitutional protections of personal privacy, freedom of speech, and freedom of movement. Faced with overwhelming public anger, Shen held multiple press conferences to clarify that he only supported transparency reporting for high-risk public officials, not monitoring ordinary citizens, but the 'fifth column surveillance' scandal remains one of his most infamous political stains.
