On my way to work every single day I pass by a normal looking elementary school (California btw and in a “middle class” neighborhood) that I notice had multiple SUV type vehicles that look like black and white police cars (mounted lights on top included) but with the words PATROL written on the side. There’s usually 3 of them all parked in a neat row in the faculty parking lot, though on occasion I do see one of them driving around the area, usually with a mile or two of the school.
What exactly is their purpose? Why does an elementary school need a police style SUV?
Why does it need THREE of them?
Why are the cars patrolling around occasionally anyway?
