Taking videos of teachers on mobile phones when they punish students or take action against them is a crime, and posting it on social media is a bigger crime that is punishable under the law, a legal expert has said. â??One must take into account the intention of people behind filming such incidents, but they must k**w that posting such video clips on social media is a violation of the law, whoever it is,â?* Abdul Rahman Masaad Al-Muhamadi, a member of the Arab Lawyers Union (ALU), was quoted as saying by local media on Sunday. Any such video, to unveil a violation, must first be shown to the supervisory body, such as the headmaster or headmistress of the school or any other competent body.
