I agree about making noise might deter most thieves. I put a pin long through my swing away and it could be busted off but by the time they get through both locks they've worked for it. On the swing away tongues it occurred to me that a person could remove the pin, undo the bolt and at their own tongue if they were that prepared even with the other two locks. So I lock the receiver, the tongue and the swing away part. None of these locks seem super strong, but they would be a pain in the butt. You can't stop the best crooks but you can try to keep most people honest.
