If this covers video, be ready for lawsuits against everyone who have security cameras with coverage that include public area ;p
If it doesn't cover video, people can just record video while walking around and pick favorite frames later ;p
Maybe it's the intent, rather the letter of the law that is important. Of course you can't police this 24/7 for every square inch of the land, but it allows someone, say, a young lady who was wearing a miniskirt, to go to the police should a random guy be taking photos of her. Probably be an extra law to throw at stalkers too, and maybe paparazzi who do a Lady Diana type pursuit of popular people.
At least I hope this is the case. If not, then there are going to be some tourists who will enjoy a Government sposored guided tour of the local jail ^-^
Hmm... that is a bit silly. I position my camera, wait till there are no one around and ready to shoot, just as I press my shutter button, someone walked into the frame... and I am breaking the law?
I sure hope Singapore don't have this law passes down... or frankly speaking, I can only shoot in the dead of the night and having sent a couple of my friends to scout entire ten kilometers to ensure that there are no one around, before I can shoot. And after that... when someone show up in my photo, I know it was not human.
