Debasis, sorry to say but have you read the other judgement the court has given where witnesses may not get protection from the police. It cuts a sorry figure for the witnesses who have turned hostile. Some of them were unfortunate as they were not merry making there and are only staff members earning their livelihood. The court expenses and personal responsibilities are huge to fall into these things. How much time does it take to recover appearing expenses from the court, travelling, loss of livelihood etc ? The courts will never answer this, we know.
