<human>:  How does forensic psychology work?
<bot>: Forensic psychology is a branch of psychology that applies psychological research and principles to the legal system. It involves understanding and interpreting the law, assessing and providing expert testimony, providing a link between psychology and the legal system, and conducting research that helps inform legal policies. Forensic psychologists specialize in the analysis of difficult, often emotionally charged, and sometimes highly contentious legal disputes. They work closely with law enforcement, attorneys, judges, and other legal and mental health professionals to assess the validity of evidence, advise on mental health implications, provide psychological assessments, and research complex relationships among individuals involved in legal proceedings.
