Photographing Buildings, Football Grounds and Interiors
Property owners have no right to stop people taking photos of their buildings, so long as the photographer is standing in a public place (e.g. the road outside).
However, if you're standing on private property and the landowner/occupier objects, then they have every right to request that you stop immediately and ask you to leave if you refuse.
Many museums, art galleries, football grounds, concert venues and similar places ban photography as a condition of entry, so you can hardly complain if you get turfed out after you've whipped out your camera.
The same applies to all private property open to the public in general - e.g. offices, shops, even your local chippy - with the owner or occupier having the right to demand that you stop taking photos and get the hell out.
Most shopping centres and malls stand on private land with many gaining a notorious reputation for speedily dispatching stroppy security guards demanding that you stop taking photos.
The irony that they're already busy filming you from every angle via a flotilla of CCTV cameras is generally lost on them.
