Knowing the distinctions between reasonable suspicion and probable cause are essential, foundational aspects of criminal justice, just as mens rea and actus reus were in your studies last week. Reasonable suspicion is an objective belief by an officer that an investigation needs to be conducted into a potential crime. Probable cause is the standard required for arrest. Keep these distinctions clear in this week’s presentations and in your criminal justice career. Support your responses with credible sourcing, either from the required readings this week, or from independent research that you conduct in the University of Arizona Global Campus Library or online, and properly cite any references.

  • Address what happens in court to a criminal case when an officer does not possess reasonable suspicion or probable cause.
