Finally, the most important lesson of all is the need to open the lines of communication. Law enforcement must stop acting as the overbearing parent. Telling a community what their problems are and what the police will do to fix them does not work. We must learn to establish the second half of the communication process, listening. Find out what the community wants and act upon it.
Different things are important to different cultures, neighborhoods, races and religions.
Encourage the officers in your individual police departments to become involved with the communities that they patrol. It is impossible to learn about the culture of any community from the inside of a patrol vehicle. Officers must be directed to get out of the vehicle and spend time talking and listening to the community. Trust the officers on the street to make the right decisions. Push as much of the decision making process as far down the chain of command as possible.
