How the police system is restricted by the Constitution as a single and stand alone system

Remember, this is a three (3) page research paper on how the police system is restricted by the Constitution as a single and stand alone system and then how it is dependent on the other cogs in the Criminal Justice System. Those cogs are the correctional systems, and the court systems. Again, I would start the paper with a sentence much like: Within the criminal justice system, the police are restricted by the Constitution and Bill of Rights in all actions taken. These restrictions are………………………… OR Within the criminal justice system, the police are guided by the Bill of Rights in all actions. This is often observed…. So…. use the court cases to indicate how … look at the 4th Amendment for guidance and write a clear and concise paper. You MUST have a cover page that includes your name, the course name and number, the semester and the year. You need a reference page… these are not included in the three pages. Make sure to expand the restrictions of police action based on the 4th Amendment and use appropriate court cases or statements.
