I don't really think it is Singapore's law. Its more of human
law and thinking to assume the accused is guilty until proven
innocence.
Its rather common for the general public to cast a condemning mind
and attitude towards the accused even before he/she/it is found
guilty. When he/she/it is guilty, then will those people be
justified in their actions and thoughts towards the accused.
HOWEVER IF the accused is innocent of the case, then the whole
scenario will somehow be erased cleanly, albeit slowly. Though it
WILL not so in the minds and hearts of those who have initially
condemned the accused.
