What does Signal 87 indicate is necessary?

Signal 87 is specifically used to indicate that a backup officer is needed. This signal is critical because it alerts other units in the vicinity that an officer may require assistance for various reasons, ranging from handling a situation that is escalating to needing help for safety concerns. It highlights the importance of officer safety and ensures that backup can arrive in a timely manner to support the officer who has called for help.

In the context of law enforcement communication, prompt and effective utilization of signals like Signal 87 can significantly enhance response times and ensure that officers are not left alone in potentially dangerous situations. It establishes a clear, standardized way for officers to communicate their need for assistance without having to detail the situation over the radio, thus maintaining focus on the incident at hand while ensuring that help is on the way.
