lets not pretend there hasnt been plenty of "family" pits, that have killed babies & adults..
few dumb ass pit owners have even tried blaming the dogs attacking/killing, because of thunderstorms.. 
and, for the record.. i honestly have nothing against dogs.. but, pits are retarded as hell.. and, will snap at any given moment..
I have owned many dogs including a pit. I now have 2 American bull dogs and I have never once seen a dog "snap." Dogs don't snap. That shyt is the owner not taking responsibility for their neglect as an owner. The signs are always there just like with this lady. The dog tried to kill everything in the house but this is labeled as a snap? Hell nah
When you have an aggressive dog you know. I have had 2. A chipoo who was so off the chain I had to eventually give him up and one of the bullies I have now. She use to fukk my chipoo up whenever he got our of line with and will go for any dog. So as a response owner, I keep her away from other dogs and small children. Although she has never shown aggression to children I know that they make her nerveous so I error on the side of caution and make sure I touch her face and tail constantly so she's okay with that type of touching. It has made it so when kids do run up to her it's not a problem.
That is what people don't do. I can tell you as someone who visits the dog park regularly that there are many people who have aggressive dogs but play dumb. I have had quite a few dogs of all breeds try and snap at my male dog who is completely friendly. And I have cussed a few people out over it. I went at it with this pitt owner because I knew her dog was aggressive but she got an attitude because I wouldn't allow her dog to play with my dog. People are trifling.
