During the course of any job, a person may eventually encounter things that might shock them. Many men and women who choose a career as a police officer can often suffer from post-traumatic stress disorder due to the levels of violence they see throughout their daily lives. If a person has suffered from traumatic experiences previously in their life, they may be at greater risk of post-traumatic stress disorder (Risk, 2010). Police officers suffering from post-traumatic stress disorder may also act differently toward citizens and in other aspects of their work. In many cities, a large number of police officers may suffer from PTSD as a result of their careers in law enforcement. Post-traumatic stress disorder also affects the way a person lives, acts, and how they will continue their life after something disturbing has happened. There are different ways a person can develop this disorder and different ways to live with it. Post-traumatic stress disorder was first discovered in traumatized American soldiers during wars because it can develop when a person has experienced or witnessed a traumatic event. and felt, according to Nancy Davis, “intense fear, helplessness, or horror.” Many officers may suffer from PTSD as a result of life-threatening situations, such as shootings, fires, and car accidents. These incidents can cause the development of more serious PTSD, which is more difficult to treat than less severe cases. Police officers experience high levels of stress during their workday. This stress can affect their family as well as their work ethic. High stress levels can be another factor in post-traumatic stress, because when officers witness disturbing events, they may become stressed about that event. Many agents may suffer from paperwork issues... which can overwhelm them and lead them to make a corrupt decision. Additionally, seeing upsetting events can cause a person to take it upon themselves to become depressed and feel guilty, which can make family and work relationships different because of how the person reacts. Post-traumatic stress disorder can vary by gender. and sometimes even ethnic origins. After studying the roles of gender and ethnicity in post-traumatic stress among police officers, "we found that self-identified Hispanic American officers had greater PTSD symptoms than self-identified European officers- self-identified Americans and African Americans” (Risk, 2010). . It was found that among Hispanic American officers, more wishful thinking and self-blame, lower social support, and greater perceptions of racism were significant variables (risk, 2010).
