I am not sure how this rule applies in Singapore or it is true.But it is definitely good news to photographers on our rights to take photos of restricted building in public places.
Some write up extracted from the rule. For the full writeup, you can go to http://www.petapixel.com/2011/01/27/...ntent=FaceBook
1. We reported in October of last year that a lawsuit by the New York Civil Liberties Union against the US Government ended with a settlement upholding the right to photograph and film in public spaces outside government buildings. The US Department of Homeland Security also agreed to notify its officers and employees in writing of the “public’s general right to photograph the exterior of federal courthouses from publicly accessible spaces”
Now, a redacted version of the directive sent out last year has been made public.
2.absent reasonable suspicion or probable cause, law enforcement and security personnel and [sic] must allow individuals to photograph the exterior of federally owned or leased facilities from publicly accessible spaces.
3. This is good.
It is important that law enforcement and PSOs uphold the public’s general right to photograph the exterior of federal structures while being vigilant with respect to suspicious indicators of terrorist or criminal activity.
[...] officers should not seize the camera or its contents, and must be cautious not to give such ‘orders’ to a photographer to erase the contents of a camera, as this constitutes a seizure or detention.
4. Given the many reports of harassment, we encourage photographers to carry this directive with them, particularly if they intend to take pictures where they’ve had problems in the past,
