Police supporters and law enforcement experts say that the claims, which can cover medical costs plus awards for an officer's pain and suffering, are needed to help officers who develop psychological problems such as post-traumatic stress disorder. PTSD is generally associated with soldiers in war zones, but is gaining more widespread acceptance as a part of many police officers' lives. Advocacy groups say that as many as 19 percent of all police officers in the country suffer from PTSD, which can be brought on by the steady pressure of facing danger while enforcing the law.
