It looks like the call returns a single object, so the following should work:
success: function(result) {
console.log(result.response.raw_message);
}
When troubleshooting this type of thing, you should set a breakpoint in your callback and then simply look at what the result variable contains.
BTW, the jQueryRANDOMNUMBERSHER(...)
in the response is because the call is invoked as a JSONP request.
