Written by Isabelle Cheng. On 31 August 2017, Nguyen Quoc Phi, an undocumented Vietnamese worker, was shot dead by a policeman in Hsinchu, northern Taiwan. Public responses to Phi’s death were polarised between pro-police campaigners, who supported the police’s use of force, and human rights activists, who emphasised the plight of migrant workers who are exploited by brokers and employers and who are regulated by a hostile guest worker system. This polarisation is also evident in cyberspace. The reporting of Phi’s death in September 2017, the sentencing of the policeman in July 2019, and the deaths of George Floyd and Rayshard Brooks in the U.S. in May and June 2020 prompted Taiwanese netizens to comment on PTT.
