Probable cause is simply a legal necessity under the Fourth Amendment should be normally accomplished even before police officers would an arrest or would conduct a research or receive a warrant. Court of law normally do find probable cause when there lies a justified basis especially in believing that a crime has likely been committed or when any scale of proof behind a crime committed is present at the place that would be searched further (Clancy, 1994). Usually a probable cause is being established through factual evidences, but not haunches. Furthermore, there does not exist any proper standard of amount for probable cause, it just simply means to be flexible because there does not exist any two similar crimes.
