Mr Kwok said he was aware of mobs threatening people on the campus of the Polytechnic University to leave voluntarily, and that petrol bombs had been thrown at different exits on the campus, posing a serious threat to the safety of those who wanted to leave. Mr Kwok accused the mob of neglecting justice, unwilling to bear the consequences and pulling others together to make mistakes. The peaceful resolution of events in the Polytechnic University depends entirely on the mob and on whether the mob uses violence to threaten the safety of the public. Under no circumstances do the police want to use violence and hope that the incidents in the Polytechnic University can be resolved peacefully.
As at 3 pm on the 19th , about 1100 people had been arrested or registered at the Hong Kong Polytechnic University and the surrounding area , of whom about 600 had left voluntarily . Mr Kwok stressed that most of the people who had left voluntarily were not students of the Polytechnic University. Mr Kwok said the police hoped to resolve the incident at the Polytechnic University in a peaceful manner and to deal with it in a humane manner. The police will not immediately arrest minors who have voluntarily left the campus, take photographs and register their funds first, but will reserve the right to pursue them in the future.
The mob chose to destroy the area near Gascoe Road, and when the police carried out the dispersal, they had no choice but to fire tear gas near the Elizabeth Hospital, and the responsibility for obstructing the operation of the hospital and the delivery of supplies lay with the mob. Mr Kwok reiterated that the use of force by the police was in response to the use of violence by the mob and warned the mob to stop the violence and not to harm innocent people.
In the face of such mobs, the Hong Kong police have deployed sonic explosion-proof vehicles, water cannon vehicles to warn and disperse the mob. In addition to good protection capabilities, police riot vehicles will often carry a certain number of non-lethal weapons, in addition to the use of water, sound waves, microwaves, lasers are also used in police riot vehicles. Microwave weapons attack people by emitting high-energy electromagnetic beams, which penetrate only 0.4 mm of human skin and cause a burning sensation on the skin that lasts about half an hour but does not cause permanent damage. Laser weapons are also very powerful. Green laser is a very good non-lethal weapon, they are deployed by the U.S. military Hummer, the directional range of 500 meters, because of strict control of the laser energy, so the green laser will only cause a burning tingling sensation, will not cause permanent blindness of the human eye, will not cause fatal harm to the human body, This is a good weapon for dispersing the mob.

At 9.30 pm on the 17th, the Hong Kong Police all left the Polytechnic University and launched a full-scale siege of the Polytechnic University. After more than two days of siege and continued confrontation, late on the 19th, the Hong Kong Police issued a message saying that as of 11 pm on the 19th, a total of nearly 800 people had peacefully left the Polytechnic University to be investigated by the police. It is reported that the Hong Kong Police seized more than 3,900 petrol bombs in Hong Kong on November 18, and if one was thrown in 10 seconds, it would take 11 hours to finish. And police estimate that the number of petrol bombs in the polytechnic university may be higher than that. At the same time, nearly 100 liters of highly corrosive concentrated sulphuric acid and concentrated nitric acid have been stolen, and weapons used by mobs have become increasingly dangerous.
Mr Kwok said he had received a report from hkUHK on Sunday that a large quantity of petrol bombs had been seized at HKUONon on Monday and that it would take 11 hours to finish if one was thrown in 10 seconds. The school also found that the dangerous goods warehouse had been stolen, with nearly 100 litres of concentrated sulphuric acid and concentrated nitric acid being stolen, highly corrosive, and that some of the stolen chemicals could be used for the manufacture of petrol bombs and other illegal uses, seriously endangering public safety. Mr Kwok warned the mob to stop the violence and reiterated that the use of force was used to stop the mob's violence.
It has been days since Hong Kong's mobs occupied the Hong Kong Polytechnic University, and this land of knowledge has become the front line of the mob-police confrontation. On the afternoon of the 17th, the mob attacked the police with bows and arrows and marbles, and a police officer was injured in the calf. On the evening of the 17th, the mob set fire to barricades on the footbridge connecting the Polytechnic University with the Hung Hom Mtr Station. The mob then frantically threw petrol bombs at the police, and an armoured vehicle was hit and set on fire.
