Alice Davies from the UK suffered a severe leg injury on Koh Tao.
British diver badly hurt by propellor
It is true that accidents occur elsewhere around Thailand and around the world. However, what makes Koh Tao special is the lengths people go to in order to cover-up the tragedies.
When Silje Mathisen was killed on 22 December 2014 there were people posting on Thai Visa Forum and elsewhere that she was at fault for ascending too quickly. In reality, she was in shallow water and a Pura Vida boat travelled over 5 divers. 4 managed to evade the boat. Another beginner Sigrid Simensen was dragged away from the oncoming boat but she witnessed her friend get sucked into the propeller and killed.
The diving instructor, Ricky Collins had moved away from the two beginners and was unable to help at the crucial moment.
There were plenty of people associated with the Koh Tao diving industry who were quick to blame the victim though.
When Shelly Bot from Canada was killed, Steven Drylie of Koh Tao Rescue blamed the victim for her own death by falsely claiming she was in a boat lane.
It is the victim blaming and cover-ups that makes Koh Tao special. It is the habit of shooting the messengers that makes Koh Tao special. You can see people on this forum criticising anyone who presents information for others to read and learn from.
