No issue. The photographers were behaving themselves on the concrete pavement. They were not squatting on the zebra crossing.
There is a wide berth for the pedestrian to cross the zebra crossing.
Pedestrians can always walk in front of the photographers without worrying about blocking their view.
As to pedestrian hesitating before crossing the zebra crossing. That is what I always do for safety. I check for on-rushing traffic.
It does not mean that just because it is a zebra crossing, the pedestrian can blindly cross and expect all speeding vehicles to stop in time for them.
one or 2 guys ok lah but so many cramped like that is a little dangerous also .... that guy at the edge of the road, yes he is ON (the very edge) the island but u all know, one accidental nudge by the photog next to him or lost balance at the wrong time when a bus is passing by and its going to be a pancaked photog under a vehicle
