This is probably an old topic. I have done my homework. There are some discussions online. I have added the links below for references.
Both discussions occurred before the protection from harassment act came into effects in 2014. I am not a law guy, but I have briefly gone through the clauses. My question is if someone can accuse me of harassment or stalking if I randomly snap a photo of him/her on the street. We can extend the discussion to any public areas. I am keen to find out the new legal landscape of street photography in Singapore. Please kindly share your insights here.
However, this discussion is not about if it is rude to take a photo of someone without seeking permission. While some prefer staged street portrait, some may prefer people in their candid status. Let's leave the choices to the photographers.
