D.C. Mayor Vincent Gray said Tuesday that he ultimately wants to blanket the entire city with traffic cameras, days after he proposed raising $30 million by installing more of the devices that churned out an estimated $63 million in tickets last year.

“Eventually, we’d like to be able to cover the entire city,” Gray told the D.C. Council at a hearing about his budget proposal for 2013. “We need to do everything we can to protect people from the negligence or irresponsible behavior of others.”
