The reference to "protect" actually was a decision by SCOTUS which was worded, as best I can recall it: "....No Law Enforcement Agent or Agency in the United States is bound legally to provide protection to any one citizen".
The aim was to eliminate litigation against L.E. for failure to protect, on an individual basis, I think. Thus, an even newer "monkey-wrench" may be thrown in: Are Firefighters "Law Enforcement"? If you say "No", look at the warnings and limitations posted publicly regarding allowed number of patrons within publicly accessed places. Or, the "Fire Protection" requirements imposed upon such places. For example, the ownership of a restaurant not having the required fire protection devices over grills, may be held liable for such omission by the Fire Official. imp
