What would you do if you were Superman?

The elephant can't hurt me so there's no problem with getting in close to it. The main problem is the civilians that it's endangering. I would fly over to Honolulu, use my super-hearing to pinpoint the elephants exact location, then pick it up and fly it over to some remote area with no other people and let it take out all of it's rage on me (since it can't hurt me). Then after some time it would eventually get tired (from all the tranquilizers and physical exertion). I would wait for it to finally go to sleep, then I would fly it back over to the authorities and let them decide what should be done with it (since Superman isn't exactly an expert on elephants...).
