A woman, a registered nurse went to the aid of the child and performed CPR until the CG came.
Perhaps no one on the crew was as qualified as the nurse and realized it. I am sure the crew has someone who is "first aid" certified, but an RN is far more knowlegeable and has far more training.

It is a sad accident, but an accident nonetheless, and it will be sad if laws are changed because of it.

Whales are wild animals. They will behave as such. They do not know there are laws stating that boats cannot come within so many yards of them, and I have been on boats where the captain wryly said, "Hey, someone tell that hunchback he's breaking the law!" We were at anchor and the whale approached US, and there was nothing the captain could safely do. No one got hurt, and it was amazing, but technically illegal!
