Saw a police vehicle in my hometown of Madison, Ind., that had two advertisements on the exterior. I quickly realized, it was a van for the anti-drug program, D.A.R.E., not a patrol unit. But that suggested that communities are missing revenue opportunities. Imagine you've just been arrested and dumped into the back seat of a police car. You are greeted with a cheery "Your arrest is brought to you by First National Bank. If you need a personal loan to post bail, use that phone call to contact one of our friendly customer service employees."
