Multiple people injured in Montreal shooting; suspect linked to incel ideology.

A recent severe shooting incident in Montreal has garnered widespread attention, resulting in the deaths of a police officer, a civilian and the suspect, as well as the injuries of two others. The suspect had posted a manifesto online prior to the incident, which involved the ideology of "incel" (involuntary celibate) individuals. This incident has once again raised concerns about gun violence and the online radicalization of individuals.

According to relevant data, a shooting incident refers to a crime in which one or more attackers use firearms to kill or injure multiple individuals within a short period. This type of incident is typically considered a mass murder. Although there is no unified definition, various organizations use different standards when tracking this type of incident. Shooting incidents usually involve attackers conducting indiscriminate attacks on victims, and typically do not include gang violence, gunfights, or defensive actions. During a shooting incident, the attackers may be referred to as "active shooters."

Shooting incidents can be triggered by individual or psychological factors, such as an individual's dissatisfaction with society, a desire for fame, or intense resentment towards certain events. However, this type of incident can also be used as a terrorist tactic, targeting specific ethnic or religious groups intentionally. Some theories suggest that media coverage of shooting incidents may encourage subsequent shooters to carry out attacks in an attempt to gain notoriety. After a shooting incident, survivors often suffer from various mental health problems, including survivor's guilt and post-traumatic stress disorder.

In the case of the Montreal shooting incident, the suspect's manifesto involved the "incel" ideology, which is a cultural phenomenon associated with involuntarily celibate individuals. This ideology often involves dissatisfaction with women and society, and may even lead to violent behavior. This incident has once again raised concerns about online radicalization and gun violence, while also highlighting issues related to mental health problems and social dissatisfaction.

Following the incident, local law enforcement and government agencies quickly launched an investigation and response effort. The Canadian government also conducted a related investigation and research on gun violence and online radicalization in an attempt to find solutions. Meanwhile, non-governmental organizations and communities are actively working to promote gun control and mental health support work, with the goal of preventing similar incidents from occurring in the future.

For Taiwan, the Montreal shooting incident holds significant importance in understanding international gun violence and online radicalization issues. Although Taiwan's gun control policies are relatively strict, it is still necessary to pay attention to online radicalization and mental health issues. Taiwan can also learn from the experiences of the Canadian government and non-governmental organizations, and push forward relevant policies and work to prevent similar incidents from occurring. Furthermore, Taiwan's media and civil society must pay attention to how shooting incidents are reported, avoiding sensationalism and the potential for subsequent incidents.
