Recent legal proceedings and public inquiries have examined the circumstances surrounding several fatal attacks, focusing on the efficacy of state surveillance and the performance of public institutions.

最近的法律程序與公眾調查研究了幾宗致命襲擊的經過，重點在於國家監察的效能以及公營機構的表現。

The inquiry into the June 2023 attacks by Valdo Calocane, a diagnosed paranoid schizophrenic, has highlighted significant systemic lapses. Evidence indicates that despite a September 2022 arrest warrant for assaulting an emergency worker, Calocane remained at liberty. Furthermore, Leicestershire Police failed to execute an arrest following a subsequent assault at a warehouse. The Independent Office for Police Conduct (IOPC) acknowledged a deficiency in the temporal efficiency of its investigations into these police actions. Additional institutional failures were noted within the Nottingham University Hospitals NHS Trust, where eleven employees were terminated for unauthorized access to victim medical records. The Crown Prosecution Service's decision to accept pleas of diminished responsibility has also been a point of contention for the victims' families.

針對 2023 年 6 月由被診斷為偏執型精神分裂症的 Valdo Calocane 所引起襲擊的調查，揭露了嚴重的系統性失當。證據顯示，儘管在 2022 年 9 月因為襲擊緊急工作人員而被發出逮捕令，但 Calocane 依然在外自由。此外，萊斯特郡警方在一次倉庫襲擊後亦未能執行逮捕。警察行為獨立辦公室 (IOPC) 承認，在調查這些警務行動時，時間效率方面有不足。諾丁漢大學醫院 NHS 信託亦被發現有其他機構失職，其中 11 名員工因為未經授權查閱受害者醫療記錄而被解僱。皇室檢察署決定接受「責任減輕」的認罪申請，亦成為受害者家屬爭論的焦點。

Parallel systemic critiques have been drawn between the Calocane case and the death of Henry Nowak, with stakeholders suggesting that such institutional inadequacies are pervasive across various UK agencies. Families of the victims have emphasized the necessity of individual accountability to catalyze systemic reform, while cautioning against the politicization of these tragedies to incite civil unrest.

Calocane 案與 Henry Nowak 之死之間被抽出平行的系統性批評，相關利益者認為這類機構不足在英國不同部門中普遍存在。受害者家屬強調必須有人承擔個人責任，才能推動系統性改革，同時警告不要將這些悲劇政治化，以免煽動社會動盪。

Conversely, a separate judicial finding in Australia addressed the 2015 fatality of Curtis Cheng. The Deputy State Coroner concluded that the attack, motivated by violent Islamic extremism, was not preventable. Although the perpetrator was associated with a group under surveillance by the NSW Joint Counter Terrorism Team, he had not been individually identified as a high-risk actor. The coroner determined that the compressed timeframe between the final planning stages and the execution of the act precluded reasonable intervention by law enforcement. The subsequent use of lethal force by a special constable to neutralize the threat was deemed appropriate.

相反，澳洲另一項司法裁定處理了 2015 年 Curtis Cheng 死亡的事件。副州死因裁判官得出結論，認為這場受暴力伊斯蘭極端主義驅使的襲擊是無法防止的。雖然兇手與一個被新南威爾斯州聯合反恐小組監察的團體有聯繫，但其個人並未被列為高風險分子。裁判官判定，從最後計劃階段到執行行動之間的時間太短，法律執法部門無法進行合理干預。隨後一名特別警員使用致命武力將威脅消除，被視為適當的。

While the Australian inquest concluded that the Cheng fatality was unavoidable, the UK inquiry into the Calocane attacks continues to uncover evidence of preventable institutional negligence.

雖然澳洲的死因研訊結論是 Cheng 的死亡不可避免，但英國針對 Calocane 襲擊的調查繼續發現有可防止的機構疏忽證據。
