香港電台報道，大律師公會及律師會一致譴責8.31在太子地鐵站的警方行動，當時防暴警察用警棍暴打跪地的乘客及施胡椒噴霧。
香港律師會呼籲有關的執法機構調查周六晚在警察局所使用的「不必要的武力」。
香港大律師公會9月3日發聲明指，近日有證據顯示，部分警員執法時，已偏離警隊一貫高素質執法的標準，特別提及於上星期六晚在港鐵太子站內的片段，「顯示防暴警察在無合理的情況下以暴力對待市民」。公會譴責「任何警隊或警務人員濫用權力的情況」，指至今只有成立一個獨立及全面的調查委員會，「找出事實的真相，才可挽回社會對警隊的信心」。全文以逾500字，列出警方濫權濫暴問題最少「七宗罪」。
聲明指，警隊基本職責是保護市民生命、安全及福社，維護治安及將罪犯繩之於法，使其得到公平司法程序處理，為法治精神重要一環。公會續指，近日有證據顯示有警員執法時已偏離標準最少「三宗罪」，過去數月有大量媒體拍攝到警務人員，於執行驅散及拘捕示威者行動時使用過分武力，包括例如在港鐵站內不合理地施放催淚彈，近距離向人群肩膊以上位置開槍，以及於拘捕時毆打被捕者，太子一夜就包括向月台上及在車廂內的乘客「以無差別的方式施放胡椒噴劑及以警棍毆打」，而其後警員離開港鐵車廂時，並沒有作出任何拘捕。
24名民主派立法會議員亦去信警務處處長盧偉聰，指8.31當日傳媒網上直播畫面可見，車廂內有市民沒有任何衝擊行為甚至跪下之時，仍被警方的速龍小隊用棍毆打，導致不少人頭破血流受傷。民主派稱過去多次要求與盧偉聰會面但未獲回覆，希望盡快會晤，討論警方濫用武力、執法缺乏準則等問題。
The Bar Association and Law Society were united in their condemnation today of police actions at Prince Edward MTR Station at the weekend, when riot police beat cowering train passengers with batons and pepper sprayed them, RTHK reported.
The Law Society called on the relevant law enforcement agencies to look into what it described as the “unnecessary force” used by the police at the station on Saturday night.
The Bar Association, meanwhile, said video footage showed “riot police launching indiscriminate attacks without any apparent lawful excuse,” flagging up that police did not even make any arrests following the beatings.
The association also complained that its members have been obstructed from assisting those arrested during protests and that “beatings upon arrests are apparent and have been widespread.”
“In the past few months, there has been a great deal of television and video footage showing police officers using excessive force to disperse protesters and in making arrests. Excessive crowd dispersal techniques have included the indiscriminate use of tear gas, including inside an MTR station, and the shooting of crowd control projectiles at shoulder height level or above at close range.”
24 pan-Democrat Legislators also wrote to the Commissioner of Police, condemning indiscriminate bloody beating of the public by the police on 31 August. They said that Commissioner Lo never responded to their repeated request for a meeting to discuss the abuse of power by the police and the lack of guidelines for law enforcement.
