Haiwainet, June 8 (local time) On June 7, U.S. Attorney General William Barr said in an interview with CBS that the pepper spray used by the police to disperse the crowd in the protest demonstration near the White House on June 1 was "not a chemical irritant". His statement not only contradicts the statement listed by the CDC, but also has been found by American media that even the companies that produce these anti-riot products have advertised that their products contain "the most effective chemical stimulants".

According to the US "Business Insider" website, Barr claimed in the interview that the police only used pepper spray and pepper balls with pepper spray and other equipment, which are not chemical irritants. Trump and other officials also said that the police did not use tear gas on the same day. But according to the US Centers for Disease Control and Prevention, pepper spray itself is a kind of tear gas, and the substances used for riot control, including pepper spray, are "compounds that can temporarily limit mobility by causing irritation to the eyes, mouth, throat, lungs and skin".

In addition, PepperBall, the company that produces pepper balls, wrote in the propaganda that their products contain "the most effective chemical irritants". According to its official website, the substance in the product is "a patented chemical irritant, which has been proved to be more effective". It is understood that this kind of pepper ball will explode and emit a choking chemical gas when contacted.

The official website also wrote: "Our product is so effective that the word 'pepper ball' can already refer to any non-lethal shooting stimulant." American media reports pointed out that the company had obtained an order worth US $650000 from the US Army in 2018, sold pepper balls and launchers to the other side, and the US military was used to control threatening targets when carrying out missions in Afghanistan.

According to previous reports, on the 1st local time, law enforcement officers used riot equipment to disperse the protesters near the White House so that Trump could cross the street to take photos of St. John's Church, and it was Barr who issued the "clearing" order at that time. Later, the White House was criticized by many parties, but Barr chose to defend the police's behavior in this interview, and said that the purpose of dispersing the crowd was to enable law enforcement personnel to establish a larger range of security lines.

However, CNN reported that the spokesman of the park police responsible for the task of the day had admitted last week that it should not have denied the use of tear gas in the process of dispersal, but this statement was soon denied again by the deputy head of the department. In this interview, Barr not only gave a denial reply, but also said that the protesters outside the White House had committed violence that day. CNN said that Barr's remarks were aimed at getting rid of the dispute that ordered the crowd to disperse as soon as possible. (Zhao Jianxing, overseas website)
