喺2019年，香港陷入逃犯條例爭議。去到7月20號，石鏡泉喺添馬公園舉行嘅一個，高調呼籲親中派支持者買藤條、塑膠水喉通等武器去對付反逃犯條例修訂嘅示威者，好多親中派參加者即場叫好。佢又話示威活動受美國惡意煽惑，行動者收受利益「亂中亂港」，形容香港現狀係「美國佬想中國死」，警告唔可以姑息丟磚塊、鐵枝嘅人。去到21號，就發生咗懷疑由疑似黑社會背景人士發起嘅恐怖襲擊事件，佢哋喺元朗站以藤條、鐵通襲擊手無寸鐵嘅市民，45人受傷，有唔少人就質疑，施襲者係咪被石氏嘅言論所煽動。
In 2019, Hong Kong was embroiled in controversy over the Fugitive Offenders Ordinance. On July 20, Shi Jingquan held a meeting in Tamar Park and called on pro-China supporters to buy rattan, plastic iron pipes and other weapons to deal with the protesters who had revised the anti-fugitive offender regulations. He also said that the demonstrations were maliciously instigated by United States and that the activists received benefits to "disrupt Hong Kong in chaos", described the current situation in Hong Kong as "United States people want China to die", and warned that those who threw bricks and iron branches should not be tolerated. On the 21st, there was a terrorist attack suspected to have been carried out by people suspected of being from a triad background, who attacked unarmed citizens at Yuen Long Station with rattan and iron tongs, injuring 45 people, and many people questioned whether the attackers were instigated by Shek's remarks.
