Has nothing to do with doing more work or paper work. If the crime was a murder for example, then yes the screwdriver would have been taken to a forensic lab for DNA or possibly prints if the the suspect was not known. For vandalism and property theft the Officers fill out a report that describes the approximate date and time incident occurred if known, what was damaged and what was stolen with the victim’s information. This is mostly needed for insurance reasons so the victim can put in a claim. The Officers might patrol the area for several weeks to show a presence and possibly catch the suspect or suspects. That’s time permitting! Keep in mind ......In rural areas one Patrol Officer might patrol a 30 mile radius or more. What folks see on there boob tube or in the movies for the most part is B.S.
