There are always at least two sides of any story. Not only is this "news" account misleading, the Old Dominion researchers are guilty of unethical research for not making clear that their study only counted the number of red light violations and was not actually a measure of intersection safety.
However, these cameras certainly do produce revenue for cash-strapped community budgets. I suspect that if one follows the money, one would find a biased funder behind this study.
