Find one single case of a burmese python released in the Everglades by an owner? None of the snakes captured in the Everglades has been shown to be a released pet. It's a lie.
There's plenty of information on how the snakes got started, please feel free to read up on it.
If you want to have a rescue for burmese pythons given to you by owners, it'll be because the state of Florida has made it nearly impossible to own them. Also it'll be difficult for you to own them, since you already need a special license to own one, and now they are going to be outlawed(except for those already owned with licenses).
