Whether or not any of us feel it is safe or unsafe to allow infants to sit in the coils of a giant python is irrelevant.
The damage is that the general public will see that video, and then immediately assume that all owners of giant pythons with small children do exactly the same thing. It makes all keepers look criminally irresponsible and hurts our overall image as a responsible keeper of reptiles.
My personal opinion is that she's a moron for allowing her infants to play on that snake. Not because it's a high probability that the snake will kill them, but for the very real possibility that the snake could kill them.
And if she came on this site and was on this thread, I would say the same thing. Shame on you for portraying us all as irresponsible!
