Police departments across Canada have cautioned secondary students against participating in a simulated elimination game due to the potential for firearm misidentification and criminal liability.

加拿大各地的警察部門已警告中學生不要參與這項模擬淘汰遊戲，以免造成槍械誤認並承擔刑事責任。

The activity, designated as 'Senior Assassin,' involves the use of water-based or pellet-firing projectiles to eliminate assigned targets, often facilitated by digital leaderboards. While intended as a recreational stress-relief mechanism for graduating students, the practice has precipitated significant security concerns. The visual ambiguity between these devices and actual firearms has resulted in multiple high-risk police interventions. Notable instances include a school lockdown in Guelph, Ontario, and an RCMP response in Strathmore, Alberta, where students were detained under the assumption that lethal weapons were present. These incidents are analyzed within a heightened security context following a mass casualty event at Tumbler Ridge Secondary School in February.

這項被稱為「畢業生刺客」的活動，涉及使用水槍或彈珠槍來淘汰指定目標，且通常配合數位排行榜。儘管其初衷是作為畢業生的娛樂減壓機制，但此舉已引起嚴重的安全疑慮。這些裝置與真實槍械在視覺上的模糊區分，已導致多起高風險的警方干預行動。顯著案例包括安大略省圭爾夫（Guelph）的一次學校封鎖，以及亞伯達省斯特拉斯莫爾（Strathmore）的一起 RCMP 應對事件，當時學生因被懷疑持有致命武器而被拘留。

Furthermore, the game has transitioned from a peer-to-peer activity to the targeting of vulnerable populations. In Kenora, Ontario, the Ontario Provincial Police have initiated an investigation into an incident where an unhoused Indigenous man was sprayed with water. Law enforcement officials have indicated that such non-consensual physical contact may be categorized as assault under the criminal code. While some community members have characterized these actions as juvenile behavior, activists have highlighted the precarious nature of the victim's circumstances, noting that exposure to water in cold temperatures poses a health risk to those lacking adequate shelter. Educational institutions, including the Kenora Catholic District School Board, have distanced themselves from the activity, asserting that it is neither supervised nor permitted on school premises.

此外，該遊戲已從同儕間的活動轉向針對弱勢群體。在安大略省基諾拉（Kenora），安大略省省警已就一名無家可歸的原住民男子被噴水的事件展開調查。執法官員指出，這種非經同意的身體接觸在刑法中可能被歸類為襲擊。雖然部分社區成員將此類行為視為青少年幼稚之舉，但社會活動人士強調了受害者處境的危險性，指出在低溫環境下接觸水對缺乏適當遮蔽處的人構成健康風險。包括基諾拉天主教教育局在內的教育機構已與該活動切割，聲明此活動既無監督，亦不允許在校園內進行。

Law enforcement and school administrators continue to warn students that the perceived harmlessness of the game does not mitigate the risk of criminal charges or tragic tactical misunderstandings.

執法部門與學校管理人員持續警告學生，遊戲表面上的無害感並不能降低被刑事起訴或導致悲劇性戰術誤判的風險。
