Bureaucrats are citing the chance of vandalism, possible crimes against persons and emergency medical services; which I guess means that normal public safety services are considered nonessential -- but lining up armed men in uniform to say "Verboten!" to members of the public wanting to pay their respects at a revered monument (one made of hard, hard rock and solidly anchored) is utterly necessary to the continued functioning of our great republic.
Okay, then. But they're gonna need taller, shiner boots.
