On Monday, we spoke with Will Humble, the incoming executive director of the Arizona Public Health Association and a former director of the state Health Department, about a proposal to ban photo-enforcement cameras throughout Arizona.

He made the case to keep the cameras on.

"Well, the data are really clear that they work, they prevent injuries and save lives, especially for the photo safety cameras at intersections, so basically the red-light cameras, the data are really clear," Humble said.

Today, we hear from the sponsor of HB 2525, Gilbert Republican Travis Grantham. His bill won House approval last week on a 32-28 vote and is now in the state Senate.
