《致香港大學李嘉誠醫學院院長、中文大學醫學院院長的公開信》

梁教授、陳教授道鑒：

　　有鑑於在六月十二日、七月二日及二十一日，香港警察濫用武力以控制群眾。如此行徑實對公眾健康遺害無窮，我們一眾醫療人員對此極為關切。作為香港大學李嘉誠醫學院院長、中文大學醫學院院長，吾等懇請兩位院長細察香港警察控制群眾之手段，以保障公眾健康。

　　據多家本地及國際媒體報導，香港警察於六月十二日，發射多輪催淚彈、橡膠子彈及布袋彈，以驅散聚集在金鐘的示威者。報導提及，警方向示威者發射至少一百五十枚催淚彈，二十輪布袋彈以及數枚橡膠子彈，造成至少七十二人受傷。從多家媒體直播可見，橡膠子彈更直射一名教師眼球，創傷嚴重，對其視力之損害非同等閒。另外，警方亦曾以數枚催淚彈包抄示威者，堵塞其退路；而當示威者被逼退守至中信大廈，警方竟朝人群中央投以催淚彈，造成數以百計的市民受傷及呼吸困難，生死攸關，不容小覷。此外，警方向一名手無寸鐵的市民，近距離發射橡膠子彈，以致其下腹嚴重受傷，情況慘不忍睹。

　　據多份醫學期刊綜述──如《刺針》（Lancet）[1] 及英國醫學期刊（BMJ (Open)）[2]，橡膠子彈乃可致命武器。同時，橡膠子彈不易操控，準確性低，有引致重傷，乃至死亡之風險。多份期刊不約而同指出，橡膠子彈不適宜用於密集人群之管制。

　　然而，香港警察漠視上述已知風險，仍於七月二日及七月二十一日繼續使用此類武器。在七月二十一日，警察更於鄰近民居之地，向群眾發射多輪催淚彈及橡膠子彈，當中更殃及記者。此等武器之禍害影響深重，不單有損呼吸系統，更會導致燒傷、嚴重鈍物創傷及爆炸性創傷。據媒體報導，武器造成至少十四人受傷；更有市民懼於警方之搜捕行動，而未敢求醫，致使受傷數字難以估算。

　　人權醫療組織（Physicians for Human Rights）醫生哈爾（Dr Rohini Haar）在接受紐約時報訪問時指出，警方對市民使用不成比例的武力，實有濫用武力之嫌。早在二零一四年，潘冬平教授[3]亦對香港警察使用催淚氣體情況深表關注，擔心催淚氣體損害市民呼吸系統。可見，催淚彈、橡膠子彈及豆袋彈等武器危害不輕，對香港市民公眾健康的損害不容置疑。

　　兩大醫學學院一直致力培育杏林菁英，不遺餘力。一眾醫療人員亦謹承《希波克拉底誓詞》之教誨，不論病患身份職要，一直為全人類之福祉著想，嚴守不懈。學院循循善誘，吾等縷心刻骨。誓詞薪火相傳，代代不息；缺少對生命健康之尊重，醫療人員何以自立？故此，我們一眾醫療人員懇請院長，發表聲明，呼籲香港警察：

一、避免濫用催淚彈及任何類型子彈，以免導致人命傷亡及其他不可見之損傷。
二、在使用武力時，必須顧及市民安全，並保持專業克制。

　　醫療人員一直存仁心，行仁術；保護市民之健康，乃至生命，吾等責無旁貸。院長為學為醫，高風峻節，茍以吾等同心同德，捍衛市民之生命健康，必見杏林春暖。

　　謹祝
道安

一眾醫療人員謹上

Dear Professor Leung and Professor Chan,

We are a group of healthcare professionals, some of us being also graduates from the Faculty of Medicine of the University of Hong Kong and the Chinese University of Hong Kong. We are writing to express our gravest concerns over the persistent and serious threats to the health of members of the public posed by weapons deployed in crowd control by the Hong Kong Police Force (HKPF) on 12 June, 2 July and 21 July. We hereby urge the Deans of the sole Faculties of Medicine in Hong Kong to take actions in censuring the HKPF and the Hong Kong Government against the serious health risks in their crowd-control tactics.

On 12 June, as reported by multiple local and international news agencies, the HKPF fired multiple rounds of tear gas, rubber bullets and bean-bag rounds to disperse protesters in Admiralty. Over 150 canisters of tear gas, 20 bean-bag rounds and several rubber bullets have admittedly been directed at protestors which resulted in at least 72 injuries. As evident in the live reports from various media sources, a teacher suffered traumatic ocular injury causing significant vision loss when his eye was hit by a rubber bullet; hundreds of citizens suffered various degrees of injuries and respiratory distress consequential upon the numerous tear gas canisters shot at Citic Tower in Admiralty where protesters were trapped in a life-threatening space filled with tear gas; an unarmed man sustained injury in his lower abdomen when a rubber bullet was directed at him in a short distance.

According to multiple studies and reviews from high impact factor medical journals, in particular the Lancet[1] and BMJ (Open)[2], rubber bullets can be lethal. Their notorious inaccuracy and risk of severe injury and death render them inappropriate and unsafe means of force in crowd control.

However, despite the known risks of these weapons, the HKPF tenaciously deployed them on citizens on 2 July and 21 July. On 21 July, 55 canisters of tear gas, 5 rubber bullet rounds and 24 sponge bullets were admittedly shot, some without immediate warning, at protestors and even at journalists notwithstanding the numerous residential buildings and citizens in the vicinity. The use of these weapons has left members of the public with at the very least, various types of injuries and further, burns, blunt force trauma and explosive injuries. 14 injuries have by far been reported where others did not present themselves to the hospital in fear of the risk of prosecution.

Dr Rohini Haar of Physicians for Human Rights had in a recent interview told the New York Times that the force used by the HKPF was disproportionate and excessive. In Hong Kong, Professor Ronnie Poon had as early as in 2014 expressed openly his earnest concern over both the short term and long term health risks in the use of tear gas in particular to one’s respiratory system when the HKPF first fired tear gas at Hong Kong citizens [3]. It is indisputable that these named weapons put the health of Hong Kong citizens at serious risks.

Doctors have striven to stand by the Hippocratic oath that they remain members of society, the identity of which comes before their profession, with special obligations to all fellow human beings. The two medical schools in Hong Kong have been established accordingly for the nurture of healthcare professionals to serve the public with benevolent hearts and minds. This is the time to honour our oath that human life should deserve the utmost respect and to maintain by all means such noble traditions of the medical profession.

We, as healthcare professionals, therefore implore the Deans of the only Faculties of Medicine in Hong Kong, in the service of humanity with conscience and dignity, to take the lead in safeguarding the public’s health and to issue a statement to urge the Hong Kong Police Force to:

(1) refrain from using tear gas and bullets in any form on protestors to prevent further bloodshed and severe non-reversible injuries; and

(2) exercise due restraint over the use of force when handling protests and at all times, put the safety of Hong Kong citizens at the highest priority.

Regards,
A group of healthcare professionals

Healthcare professionals have a social responsibility to safeguard the health of members of the public. We believe that, as Deans of the faculties of medicine in Hong Kong, Professor Leung and Professor Chan bear a paramount obligation in this regard. We appeal to all healthcare professionals to join us in this petition to urge the deans to issue a statement to honour their obligation to defend the public from health risks.
