A democratic government, like all governments, must protect itself, but must be constitutional, open and unaffected by political intrigue. That is the purpose of the judiciary. The main function of the judiciary is to explain and monitor law enforcement. Firefighter sometimes i look back on my life poster. Why does the law need to be explained?
