I live in a small town of like 11,000 people and they always send 5 or 6 cops to a call. It doesn't matter what the nature of the call is. You see 3 in a row roll straight out of the police station and follow right behind one another. Then two more will trickle on other later on. Then in the bigger cities with 100,000 people you'll see one cop at a wreck. Lol
small departments are bored. They've even admited that to me when I asked. lol
It's a waste of tax dollars. They also do this to justify their yearly budget.
