Body language has seen use in the area of law enforcement. The relevance of body language in this area can be seen in the numerous Federal Bureau of Investigation (FBI) Law Enforcement Bulletins   that have included it in their articles. The application of body language in law enforcement goes both ways. Members of law enforcement can use body language to catch unspoken clues by suspects or even victims, this enables a more calculated and more comprehensive judgement of people. The other side of body language is that of the investigators' themselves. The body language of the members of law enforcement might influence the accuracy of eyewitness accounts. 
Objects and images are also tools that can be used to communicate nonverbally. On an online forum, for example, you might select an avatar to represent your identity online and to communicate information about who you are and the things you like. People often spend a great deal of time developing a particular image and surrounding themselves with objects designed to convey information about the things that are important to them. Uniforms, for example, can be used to transmit a tremendous amount of information about a person. A soldier will don fatigues, a police offers will wear a uniform, and a doctor will wear a white lab coat. At a mere glance, these outfits tell people what a person does for a living.
