If somebody's dogs got after my livestock or anything that belongs to me I would use whatever is closest for me to get a hold of.
Did she tie the dogs off and beat them to death with the bat? If that's the case she is completely in the wrong, however, I don't believe she will get in trouble but you probably will. That is how it usually goes!
x2...catch type dogs need to be kept where they can not get loose because they can and will kill livestock including dogs, chickens, and they could get on someones child...
