This is not the first time and definitely will not be the last time. Police lied through their teeth that they charged at peaceful Malaysians singing Negara Ku. Read what the Selangor Police Chief Khalid Abu Bakar has to say as reported by Malaysiakini:
Selangor police chief Khalid Abu Bakar has denied that the police moved in on participants at a candle-light vigil last night while they were singing the national anthem.
“That is what they (participants) are claiming,” Khalid told reporters at the Petaling Jaya police district headquarters about midnight.
When told that there was a video recording of the police action, Khalid replied: “I am denying it.”
