The police power to control the use of private property exceeds any authority granted by the Constitution. It immediately induces an interests on the part of civic agencies adverse to their mandates. There is no doubt however, that civil society has a rational claim for an owner to account for distributed risks associated with their operations. Civil means to manage such competing claims and intangible risks are therefore necessary. If you asked me what were the necessary structural changes needed from Congress, I would tell you tort reform and insurance deregulation.
