You said my English is poor so I am looking forward to your excellent and fluent English. Come on , don't let me down!
721 was a provocation caused by yc, and it's rather ironic that you think the police should have come and save the yellow ass. You yc started a war and lost like ugly monkies. Why would you expect the police to save you? Losers.
As said by the police, most police force was allocated to the main protest areas so there was not enough time to send police over to this sudden attack scene. Everything was caused by the stupid yellow yc and it is ashamed for you to blame the police for what you have caused. Go and eat banana, monkey.
