In courtroom after courtroom, it has been proved that anti-fracking activists have been guilty of fraud or misrepresentation.

There was Dimock, Pa. — the likely inspiration for “Promised Land,” which is also set in Pennsylvania. Dimock featured in countless news reports, with Hollywood celebrities even bringing water to 11 families who claimed fracking had destroyed their water and their lives.

But while “Promised Land” was in production, the story of Dimock collapsed. The state investigated and its scientists found nothing wrong. So the 11 families insisted EPA scientists investigate. They did — and much to the dismay of the environmental movement found the water was not contaminated.

There was Wolf Eagle Environmental Engineers in Texas, a group that produced a frightening video of a flaming house water pipe and claimed a gas company had polluted the water. But a judge just found that the tape was an outright fraud — Wolf Eagle connected the house gas pipe to a hose and lit the water.

Other “pollution” cases collapsed in Wyoming and Colorado. Even Josh Fox, who with his Oscar-nominated documentary “Gasland” first raised concerns about flammable water, has had to admit he withheld evidence that fracking was not responsible.
