So often I think government is about the path of least resistance. Just get by with the least amount of conflict or work. Too many snaggers, shut down the river rather than enforce the law. Tribes threaten to sue, give them what they want. Someone threatens to sue, just give the person what they want. I first saw this with the parks department. People vandalize the bathrooms, lock them up or remove them. Never mind that only .1% of the population is the problem, it is just easier to shut something down than actually do something about a problem.
