Fighting back costs money. Few can afford it. The Parks service, which has used photography and statistics to measure crowds for decades no longer does so. Luis Farakahn sued when they reported his million man march was about 120k. They didn’t have the money so the service changed the count to a million and then stopped counting. Once you start a lawsuit, the only way to limit the cost is to settle out of court. It sucks, but that’s reality.
Of course, that's a sad reality of our civil court system. However, the mega companies have the funds to force the commies like greenpeace to settle, also. It goes both ways.
Energy Transfer Partners has the deep pockets to take Greenpeace to hell.
