Communication between individuals on the force varies considerably. There is a strict hierarchy in the force, as most people are aware of, claims Officer Friendly. Thus, a person does not speak to their superiors the same way as to coworkers or subordinates. It is important to maintain this hierarchy because it helps the officers have a chain of command that includes respect for authority. Without authority, there would be too much dissention when making critical decisions. Decisions in the force are life/death decisions, notes the officer. There is no room or time for democratic discussions. Officers need a clear chain of command so that decisions are swift and authoritative. To carry out the functions of modern police work, all cops must work together and be on the same page. There is a great degree of collaboration, in spite of the hierarchy. "Officers need to work together, we're in this together," Officer Friendly stated.

Other special units need to be informed continually of what is going on, and how investigations are proceeding. The need for communication in law enforcement is "tantamount" to other types of issues in the subculture, states Officer Friendly. Communication means that all information is shared openly. It also means that reports are filled out consistently and in a manner according to proper procedure. When law enforcement officers communicate with each other, they can reduce casualties and maximize successful arrests. Working as a collective force in the criminal justice system ensures the safety of all citizens in the community, which is why Officer Friendly also advocates cooperation and communication with citizens. "Modern policing," states Officer Friendly, "must be legitimate through interactions with community members."
