 I'd say that the argument that the weather was the major cause of the drop in fatalities is as flawed as that attributed by some to Hants Police. 
 Read the press release again. 
 All that it says is that deaths were down and that extra attention had been paid over the year to popular biking roads to TRY to reduce them.
