“..His business, his rules—For better or worse.
Of course, that extends to all businesses in their dealings with the public...”
yup - private property is sacred.
While private property is generally sacred,.even our founders recognized a few exceptions (seach warrants, eminent domain).
The bigger issue, IMHO, is the centuries upon centuries of common law protections in regards to contract law which started coming undone with the civil rights act.
Historically, a contract was not considered valid if there was any element of coercion. Contracts are supposed to be entered into freely by the signatories. When special protections were given by fedgov this was turned on it’s head. Suppose for example, a WWII prisoner from the Pacific theater returned home with a bitter hatred of the Japanese. Over the years, he acquires some rental properties and is approached by a prospective Japanese tenant. Barring any other groundsfor refusing the rental, the landlord is effectively coerced to contract with the Japanese against his will, lest the full force of fedgov come down on him for discriminating against somebody’s national origin.
Bottom line, if this d-bag has personal issues with police, he should be allowed to refuse service to anybody he pleases. By that same token (pun intended), I would hope the local police fully respect his antipathy towards them when responding to any issues on his property.
