I think you are incorrect. There are incidents of terrorist attacks on pilgrims many times. There is a very high security cover for the pilgrims in Kashmir and the vehicles move in groups. They don't travel after sunset and are forced to security protected buildings like schools, play grounds, etc, provided food, blankets, and allowed to move only in the morning after 8.00 AM. It is not that pilgrims can freely go and have a darshan in Amarnath.
