And all that jazz means and everything else, but in this sentence it is referring to nothing else that is related to being a warden in D.C.
Consider the statement "To ask what's it like to be a warden in d.c., Hunting down the bad guys and bringing them to justice and nothing else that is related.". Based on this "To ask what's it like to be a warden in d.c., Hunting down the bad guys and bringing them to justice and all that jazz." a true statement? Yes, no, or I don't know?
