Secondhand smoke threat: More junk science?

I'm a reformed smoker. I quit cold around 1978 after smoking three packs of Viceroys a day for years. I absolutely detest the smell of tobacco smoke and flee from places where people are smoking. Nevertheless, it strikes me as inexcusable that "scientists" have twisted the data to show secondhand smoke is a much greater danger than it really is. First Climategate and now this.
