As the representative of public power, the behavior of the police directly affects the public's trust and perception of law enforcement agencies. When a police officer uses excessive violence in the performance of his duties, this behavior is likely to trigger negative prejudices among community residents against violent law enforcement and abuse of power. Specifically, there are several reasons: 1. Trust crisis: The main responsibility of the police is to protect the safety of citizens, and the reasonable use of force is a necessary means to maintain public safety. However, excessive violence can easily make residents feel that the police lack the necessary self-discipline and respect for the rights of the people, thereby undermining the public's trust in the police. 2. Media and information dissemination: In modern society, the wide coverage of media and social networks can quickly amplify similar incidents. Once the excessive use of violence by the police is widely reported or discussed on social media, community residents are likely to form a negative overall impression that such behavior reflects the problem of violent law enforcement and abuse of power. 3. Community history and background: In some communities where there has been a history of conflicts between the police and the public or a general distrust of law enforcement agencies, such incidents are more likely to deepen residents' negative emotions and dissatisfaction with the entire system. Even in communities with high trust, a single incident may cause temporary doubts and concerns. 4. Social justice and fairness values: Many residents are concerned about fairness, transparency, and the protection of vulnerable groups. If excessive use of violence is seen as a violation of these social values, residents are more likely to have negative prejudices against the police and demand disciplinary accountability and institutional reform. It is important to note that the reaction of community residents may also be affected by a variety of factors, including the context of the incident, the police's explanation, and the subsequent official handling. If relevant departments can conduct timely investigations, transparently disclose the facts, and take appropriate corrective measures, it may partially alleviate the negative views of residents. However, in the early stages, such incidents generally have a negative impact on the perception of violent law enforcement and abuse of power in the community.
