Story from AZ republic (via Tucson Citizen site; i don’t see it online otherwise. Also it ran in condensed form as an east valley brief 2/14/2012) Mesa traffic cameras to stay 2 more years.
Story mentions the Sean Casey fatality from 2005 where a junior high school student was killed while walking his bike through a crosswalk with a green light when he got whacked by a motorist who ran a red light. This whole story seems to have been a huge miscarriage of justice. A judge dismissed neg hom charges against the driver. And to add insult to injury, according to news reports the driver did not even pay her fine, or attend traffic school as ordered.
In any event the gist of the story is camera enforcement (among other factors) is credited with reducing crashes, according to Mesa Police commander Bill Peters: “Crashes at intersections now monitored by cameras dropped from 694 in 2005 to 370 in 2010, Peters said.”
