Obama EPA: Nazi Death Camps Revisited

A lawsuit was filed against the Obama EPA. The EPA was performing experiments regarding the lethal dangers of diesel exhaust. This is what the suit says:

"The suit accuses the EPA of paying as many as 41 participants $12 an hour to breathe in concentrated diesel exhaust, for as long a two hours at a time. The exhaust was directly piped in from a truck parked outside the Chapel Hill facility. According to the lawsuit, the fine particulate matter, called 'PM2.5,'  was piped in at levels 21 times greater than what the EPA calls its 'permissible limit'.”
