In Hong Kong, Some Activists Fear Academic Freedom Will Suffer Under National Security Law VOA News When lecturer Shiu Ka-Chun received a letter from his university last week, he was shocked to find that he had been effectively fired. Shiu, also a legislator, has taught social work at the Baptist University of Hong Kong for 11 years, where his teaching had been consistently rated as excellent. He was jailed last year for "inciting public nuisance" in the 2014 civil disobedience Occupy Central movement and after his release, he was removed from teaching dutiespending disciplinary proceedings linked to his conviction. Shiu said his effective dismissal amounted to "political persecution" but the university gave him no explanation. He said he felt "angry, upset and insulted." The university declined to comment on his case. Law professor Benny Tai, one of the founders of the 2014 occupy movement jailed last year on public nuisance charges for his role, was also fired by the University of Hong Kong last week. Tai lamented that academics in Hong Kong are "no longer free to make controversial statements about politically or socially controversial matters." Shui and Tai's dismissals occurred the same week as the arrests of four students on national security charges, the disqualification of 12 pro-democracy legislative candidates and news of Hong Kong police issuing arrest warrants for six Hong Kong activists abroad. The incidents took place within a month of the passing of a strict,broadly definednational security lawthat, among other things,bans acts of secession, subversion, terrorism and collusion with foreign forces. Although Tai's dismissal was widely consideredanindicator of the demise of the city's academic freedom, China's liaison office and the Beijing-owned press in Hong Kong triumphantly declared it as "a deed of justice" for an academic who hasspread "poisonous" political thinking among youngsters. TheWen Wei Ponewspaper compared Tai's dismissal to the removal of "a poisonous cancer" and portrayed Tai in a cartoon as a virus being dusted away by a broom. Hong Kong and Chinese officials have escalated their rhetoric on the education sector in recent months, accusing teachers of "inciting" anti-China sentiments and encouraging students to oppose the authorities,and blaming them for the mass, anti-government protests last year. The national security law is aimed at stamping outactivities likethe pro-democracy protests, which turned increasingly violent as frustrations mounted. Hong Kong's top leader,Carrie Lam,told a forum days after the national security law was passed last month that social movements, from the Occupy movement in 2014 to last year's anti-government movement,indicatethat "anti-China forces have infiltrated school campuses." .
