Hi, as a point for clarification, Hazekang was shooting for his school publication, therefore the pass that he had flashed was not misused.
If he had used the pictures without permission, then will it be considered misuse of the pictures.
Chek Jawa is supposedly closed to public, but since there are no fences, no barricades, and even police who patrols the area to watch out for the public (not catch trespassers, but to check the area), anyone can trek in at their own risk.
It's possible to cycle, then trek a bit to Chek Jawa. But have to check the low tide timing. Do be careful of the terrains there though, there is a certain part that is quite dangerous.
