Bold thievery runs rampant in the streets of Baltimore, where 136 streetlights have been stolen in the past few months. How to deal with this larceny? That's easy, do something indiscriminate and stupid. Train five solar-powered cameras on the remaining streetlights, and teach those cameras to cry out when they see anything moving around them. Stop!, shouts the camera at passersby. We have taken your photograph. We will use this photograph to prosecute you. Leave the area now!
"But Mr. Streetlight Camera, I was just tying my shoe."
How would you like to have one of these things outside your window, shouting down anything that moves all night long?
