from the 18/11 trampede incident (source from salute to hk mata), but not sure "how true":
《任何生命應當尊重及珍惜》
昨晚(11月18) 警員在油麻地執行任務時的真實故事:
這場騷亂以來 第一次為抗爭者而流淚…
這晚汽油彈如雨下 艱辛拾回的陣地很快因為彈藥有限而快將失守… 幸得STC(即速龍) 趕到協助 隨即加入追捕 控制數名暴徒後 追入後巷 眼前一呆…
因逃避追捕 暴徒於窄巷內發生人踩人事件 當處理上面一堆時 發現在最底部的一名女示威者 面部發紺 瞳孔無反應 及全身抽搐...
心知不妙 二話不說 施行急救 眼淚不自覺同時流下…
期後 女子有返生命表徵 更突然恢復意識醒過來
我:冇事喇… 我係警察… 你啱啱冇咗意識而家醒返… 你身體仲有冇其他地方痛?
她:(搖搖頭) 我可唔可以打電話報平安?
我讓佢打俾哥哥 及我同佢哥哥交待佢嘅狀況同被捕過程
她:我會唔會被強姦同被自殺吖?
我:你唔好痴線喇… 我如果想你死 我唔會救返醒你 (我都唔敢同你講 我因為你而流淚吖…)
她:我覺得你係好人…
我:呢度冇人想你死 你唔好亂諗喇…
她:你可唔可以握住我隻手?我好驚吖…
就這樣一直陪伴到救護員接手處理
她只是19歲 她只是yr 1 Social Science 上天俾個機會我救得返你 希望你好好珍惜呢個機會想想將來嘅路點樣行落去 別道聽途說我們是 殺人犯 強姦犯 黑社會…
(請手動轉)

以上是昨晚的真人真事。

Last night (November 18) The true story of the police officers performing their duties in Yau Ma Tei:
For the first time since the riot, I shed tears for the protesters...
This night, the petrol bombs were so hard to pick up the position that they would soon fall because of the limited ammunition... Fortunately, STC (Athletic Dragon) rushed to assist and immediately joined the hunt. After controlling several mobs, chasing the back lane, staying in front of you...
In order to escape the hunt, the thugs in the narrow alleys occurred in the people. When dealing with the above piles, a female demonstrator found at the bottom of the face, facial hair, pupils, no reaction, and convulsions...
I don’t know what to do. I don’t know what to do. I don’t know how to shed my tears.
After the period, the woman has a return to life.
Me: Anecdote... I am a policeman... You are conscious and your home is waking up... Is there any pain in your body?
She: (shaking his head) Can I call to report peace?
I asked my brother and I to talk to my brother about the situation and the arrest process.
She: Will I be raped and killed?
Me: You are so good to be crazy... I want to die if you want to die. I will save you and wake you up. (I dare to tell you that I am crying because of you...)
She: I think you are a good person...
Me: I want you to die, you are so arrogant...
She: Can you hold my hand? I am so shocked...
In this way, I have been accompanying the ambulanceman to take over.
She is only 19 years old. She is only yr 1 Social Science. I have a chance to save you. I hope you will cherish it. I want to think about it in the future. I don’t want to hear that we are murderers, rapists, underworld...
