I refer to the latest reports relating to the Yuen Long attacks of July 21 last year. That night, we saw how a group of about 100 people in white T-shirts and wielding rods attacked protesters returning from anti-extradition demonstrations, and other commuters, at Yuen Long MTR station. Many citizens tried to call police, but the high volume of calls jammed the emergency hotline, and it was several minutes before officers arrived. At least 45 people were sent to hospital (“ Wounds from Yuen Long station attacks are yet to heal ”, July 22). Just over a year later, on Wednesday, 16 people were arrested, including lawmakers Lam Cheuk-ting and Ted Hui Chi-fung of the Democratic Party. Lam was actually a victim of the violence. There are many videos and photos on the internet clearly showing how commuters and others were beaten and injured in the “721 incident”, including Lam and even journalists. A statement from some Yuen Long district councillors said Hong Kong police “altered history and erased facts so as to change public opinions, boost the force’s morale and comfort themselves.” I support the Yuen Long district councillors’ stance. On July 21, I was watching the live feed from the press at the scene in Yuen Long. It was very clear that those people in white T-shirts were really hitting the protesters and other commuters inside the MTR station (“ Anger mounts as police accused of trying to rewrite mob attack with arrest ”, August 26). It is also a fact that citizens could not get police to arrive sooner. Originally, I felt happy to hear that police charged some people for taking part in the July 21 attacks. It meant we would soon know the truth about the assaults. But I didn’t expect they would actually arrest victims of the violence that night. If even a victim is arrested, despite evidence such as photos and live video, how are the public to be convinced that the authorities have the ability to govern Hong Kong and protect the public? I am really worried and I hope the Hong Kong government can investigate the matter seriously. With regret, Daisy Lee, Tseung Kwan O
