Is it really illegal? Let's have a look at Laws of Malaysia: Act 574 (Penal Code):
1. An act of taking photographs does not clearly show an intent to commit an offence or intimidate.
2. An act of taking photographs does not clearly show an intent to insult.
3. An act of taking photographs does not clearly show an intent to annoy the person in possession of the space (land) which acts as a custody of the human dwelling.
Criminal-trespass is a subset of Criminal trespass - if the prosecution failed to prove that Section 441 applies to the photographer, this section will also fail to apply on the photographer. There is no conclusive evidence from the photographs taken at night that shows any proof of the photographer entering into or remaining in any building, tent or vessel used as a human dwelling. It can be safely assumed that the photographs were taken from the outside of the building, tent or vessel used as a human dwelling.
