The only problem i see is that the officer continued to shout out in Cantonese to this guy. In the past when i have stopped by police they automatically speak Chinese and assume I can speak it too (even though I can) I always reply "Eh, sorry do u speak English", I look nothing like Chinese, brown skinned so why the automatically assume i can speak it, don't they know that lots of foreigners come to HK.
I have no problem with the shooting, if i was the cop and the guy kept on going at me even after the pepper spray and baton then i would shoot as well, what if the overpowered me, took me out and then took the gun and went on a shooting spree. Who know if the guy was a Loony or not.
Safran, if u were a cop, u asked me to do something and i kept on ignoring you then i started to attack you with whatever i got a hand to which in this case is a chair, u pepper spray me, i am mental now and that will not stop me, i keep on charging you, u have no choice but to shot me, do u think i am going to stand there and be target pratice so u can shoot me in the middle region, heck no, i am going to charge your ass and beat the shit out off u, so who knows if you lost your balance and shot me in the head, maybe u were aiming somewhere else. Only the Cop knows so stop arguing why he was shoot the guy in the head.
