If Barney Fife gets stupid, you stop, you get his badge number, you call his boss (who may be stupid enought to back him), you also publish his stupidity via You Tube, he gets in trouble, and then they leave you alone. There is NO ENFORCEABLE LAW than can ban taking pictures or videos of venues and vistas from public property.
The funniest one I have heard asserted is copyright of the facade, which is of course totally specious.
Kowtowing to idiots because they have a badge, be they sworn LEOs, LPOs or rent-a-cops only reinforces their bad behavior that they can make it up as they go along.
