The Crown Office and Procurator Fiscal Service (COPFS) is the public prosecution service in Scotland. It is responsible for investigating and prosecuting crimes, ensuring that justice is served. The service works closely with police and other agencies to gather evidence and build cases against offenders. COPFS also provides support to victims and witnesses throughout the legal process. It plays a crucial role in upholding the rule of law and maintaining public confidence in the justice system. The service operates under the authority of the Lord Advocate, who is the head of the prosecution in Scotland.
