How well do police officers meet the criteria of probable cause before taking action with the regard to criminal activity?

Answer:
The wording of the question makes no sense. First off, an officer only needs to have reasonable suspicion that a criminal acltiivity MAY be taking place in order to have the authority to look into it.
After looking into the activity and finding a person, or persons, committing a crime or who he has PROBABLE CAUSE TO BELIEVE MAY have committed a crime he can then make an arrest.
