Which of the following is a recommended technique for de-escalating a hostile crowd?

Engaging with the crowd to understand their concerns is a recommended technique for de-escalating a hostile crowd because it fosters communication and helps to address the underlying issues that may be causing tension. This approach demonstrates that law enforcement or crowd management personnel are willing to listen and consider the perspectives of individuals within the crowd. By actively engaging, officers can identify specific grievances, which may be resolved through dialogue rather than confrontation. This not only helps to lower the emotional temperature of the situation but can also lead to a reduction in hostility, as individuals feel heard and valued.

Building rapport with the crowd can also aid officers in maintaining safety and order while promoting a sense of community and collaboration. Understanding the crowd's concerns allows for more effective and tailored responses, which can prevent escalation into violence or unrest.
