One of the words that keeps cropping up is "entitled". Sir Fred is no more "entitled" to extra protection than any other citizen. Broken windows generally elicit no more attention from the police than a phone call and pro forma report.
Yobbery should not be tolerated, but that's across the broad spectrum of society. If he wants ADDITIONAL protection he should do the same as the rest of us and PAY for it himself. You wouldn't get a cop stationed outside your house if you were subject to harrasment / vandalism by your neighbours, so what's the difference ?
