“Criminal law is all the law relating to crime. » (Wikipedia, 2014) This law encompasses several different aspects of our government and the means used to regulate them. Maintaining peace and public order is one aspect of this. Law enforcement officers also work to ensure the good conduct of the public. Anyone who endangers public safety is breaking this law. Punishment is used in various ways to discipline anyone who violates these laws. There are four main sources used in criminal law today: • Constitutional law – body of law that includes guidelines and rules used to ensure the correct meaning of the constitution. This law also governs actions set forth in the United States Constitution. (Wikipedia, 2014)• Administrative law – body of law that involves creating and establishing administrative agencies. The rules, responsibilities, regulations and powers used by these agencies are also developed under this law. Agencies such as the Social Security Administration and welfare commissions are two agencies included in this law. Usually, the creations of these agencies were made to provide benefits to their candidates. (School, administrative law) • Statutory law – this body of law is crucial to public safety. The functioning of our various government bodies and many of their laws are based on the above law. The pattern used for today's society and how justice is maintained comes from this law. (Demand Media, 2011) These laws are primarily written and established by government authorities in response to the needs of public or civil order. (Statutory Law – Definition, 2010)• Jurisprudence/Common law – body of law developed over time by higher courts. The laws are in the middle of paper......is this an exception with a fleeting target?
