You have to remember the complaint handler's mantra: It's not personal. Though sometimes it can seem like it, a complaint is not you vs. them. A complaint is just someone's negative interpretation of events, and it could have merit or not.
Once you realize that it's not personal, complaint response becomes a process not a confrontation. The key to dealing with any complaint is showing respect. By respecting yourself and others, everything else will fall into place.
Understanding Complaints
A citizen's complaint usually stems from a need that is not being met. If you think in these terms, handling a complaint becomes much easier.
You can show respect right from the start by trying to understand the other person's viewpoint. Please don't assume I automatically mean that you must agree with them. Understanding why the complaint is being made and agreeing with its merit are two different concepts.
One of the most common needs of a citizen who is lodging a complaint is that he or she needs to understand what is happening at the moment of police action. Remember that as officers we have been trained to do our jobs professionally. We understand what we can and can't do by way of standard operating procedures, laws, and other restrictions on our authority. Usually all the citizen knows is what he or she has seen on television, or worse, learned by way of urban myths.
