it is unfortunate that people, who had come used to visiting this particular GPO, had to see it killed like that, but wild animals kill and are killed, its natural. if a sperm whale came along and ate it there would be no fuss and rightly so. instead of condemning and threatening the young man, he should be advised and educated about making proper decisions and restraining his natural instinct to kill. THINK before you pull the trigger. anyway i hope neither him or others are put off diving over this.
