The year before last, a wave of anti-revisionist violent demonstrations prompted the police force to examine the effectiveness of low-force equipment. Last year, the police began to introduce pepper water launchers from Swiss manufacturers and carry out relevant training. The police recently arranged personnel to launch on the spot as a demonstration. The results showed that the target doll's chest was dyed blue in a strong wind environment, which proved that the accuracy of the equipment was not affected by the weather and was better than the previous equipment. The police said that the field trial plan would start on Sunday. The stormtroopers of the Hong Kong Island Region would take the lead in equipping the equipment, and would take it out when necessary. Three months later, they would review and study the next step of equipping and using the plan, in order to improve the effectiveness of riot control.

The police introduced precise anti-riot equipment, and the effect of anti-riot and anti-riot was even more remarkable. The police invited the media to the police mobile force base in Fanling the day before yesterday to demonstrate the orange pepper launcher with the gun barrel. A strong wind occasionally blew up at the scene. The demonstrator and the two target dolls were 1.5 meters and 5 meters apart. The personnel took out the equipment, first aimed at the chest of the dolls with a red light spot, and then shot blue pepper water. The white clothes of the two dolls immediately dyed blue, but there was no other damage.

Yuan Yongkang, the superintendent of the Police Mobile Force Training School, said that during the "black storm" the previous year, public and private property were repeatedly damaged, and police officers and dissident citizens were attacked from time to time. The police force needed to provide more effective low-lethal weapons for front-line personnel. After analyzing the weapons data of Swiss manufacturers last year, it was confirmed that the pepper water launchers were low-lethal weapons, and began to introduce and carry out relevant training for front-line colleagues.

Yuan also said that the pepper water launcher can fire pepper water four times after each shot, with an effective range of up to seven meters, but the impact force is not strong. The ingredient is chili oleoresin. The mucous membrane of the hit person will immediately swell, and the eyes will close. After inhalation, it will cause coughing, burning sensation on the skin and mouth and nose, and may also cause nausea. The blue dye will remain on the nails, skin and clothes, and the effect lasts for 30 to 45 minutes, It will not cause a permanent impact, which is the same as the original pepper spray and pepper ball gun, but the pepper water launcher can hit the target more accurately, and the hit rate will not be affected by wind and rain.

Yuan said that after using the pepper water transmitter and confirming that the other party was subdued, the staff would take the other party to a ventilated place as soon as possible and wash it with a large amount of water. At the same time, they asked the other party to relax as much as possible and keep breathing unblocked. He stressed that the manufacturer listed that the equipment could be launched to the head, but the police tended to require the personnel to launch towards the center of the target person's body, such as the chest. The use rules were more rigorous than those of the manufacturer, and, like the use rules of other equipment, the personnel should report to the superior once using the equipment.

The police plan to extend the application of pepper water launchers to daily police work, and carry out a field trial plan from Sunday (17th) to January 15 next year. First, let the front-line personnel of the stormtroopers of the Hong Kong Island Region be equipped when on duty. Yuan explained that due to the numerous bars on Hong Kong Island, which are easy to breed violent cases, the police chose the Hong Kong Island General District as the trial area. At that time, every police station and every assault vehicle will carry the equipment, and the relevant personnel have also understood the operation. After the trial plan is completed, the police will analyze the data collected, pay attention to whether there is room for improvement, so as to determine the next step of the allocation and use plan.

Yuan concluded that the introduction of pepper water launchers would help front-line personnel to deal with violent cases more effectively, safely and professionally, and added the option of using force. He reiterated that the police force has always had very strict rules on the use of force. As long as the citizens abide by the law and follow the instructions of the police in case of an accident, there is no need to worry about the use of force by the police.
