Not quite so obvious fuzzy - red-light cameras

We love doing the occasional 'fairly obvious fuzzy' on the show - studies which prove things that most people find obvious. We're not belittling the research, you just wonder why there needed to be three consecutive studies conducted which all proved absitance-only campaigns don't work for example.
