Actually Trisnake, you're not helping at all, and should maybe stop because I think you're getting a bit too emotionally involved in this now.
Nixon, you do the best that you are able to in whatever situation you find yourself it. That's all any of us do. If in the future you look back at whatever choice you end up making and think you made a mistake, well then, it's a lesson learned. None of us can know how a volatile situation is going to play out. For what it's worth, if you call animal control, there should not be any legal repercussions for you. @bcr229 is correct; animal abuse is a crime and you will not get yourself or your family in any legal trouble for reporting it, especially if done anonymously. You won't have any control in what happens to any of the animals after that point, so that I think is going to be the hard part. The authorities could very well euthanize the snakes, or turn them over to a rescue, or take the family at their word that's they're working to fix things and leave it that. You will probably never know, but at this point, without the support of your parents, I don't think you're going to have much ability to do anything more yourself.
