If anyone is scared of a snake "attack" from a ball python, I don't know what to tell you. Their bites are like being gummed to death by a very angry newborn baby. If you are lucky they will cut the skin and you will have a story to tell your grandchildren of the time you nearly died from a few pinprick holes in your hand.
Now if you own a full grown say anaconda or retic and you don't know how to handle it, you should not have owned a full grown anaconda or retic. Large snake attacks resulting in death or bodily harm to the point where they are in the hospital are 1000% the owner's fault for either complacency or incompetence. I am not talking about bites but of serious injury due to carelessness. that bite to the face story was totally the owner's fault for being complacent and not aware of surroundings and the snake's mood.
If you own a large species and it gets loose that is also your fault.
This is why I will not own a full size snake, I would get complacent and I am not wanting the responsibility.
In other words, operator error.
