Back to the original question. In my opinion, it's the show management and especially the JUDGE's responsibility to address these kinds of issues. If a calf has been tampered with in a way that air or whatever else is present at show time, the judge is the one to find it and then address the issue however they see fit - either by reporting it to show management or burying the calf in last place (which is exactly what I'd do if I caught a calf with air in it in the ring).
99.99% of the time these questions about "what should I do because someone did such and such" at the county level are based on rumor and not on something someone actually saw someone doing. As with any rumors, they are almost always wrong. If someone did have the nerve to air a calf (or anything else) at a show, you're sure not gonna see them doing it.
Anyone that's actually been around it understands the absurdity of these claims about airing at a show. That's not how or why its done, and when it is still done it's not to make a calf thicker, it's to make them smoother. Come show time, there's nothing there but fat and meat, that is as natural as anything to do with a show steer. Airing has nothing to do with young "jocks". I've seen more people do it that are now in their 70s than I have the younger generation. Those that are still doing it (and yes it's still common in families that have shown for generations) are doing so because that's how their grandfathers taught their fathers how to make a show steer look fat and smooth. Not because they are vile cheaters. I know plenty of folks that still do it, and it doesn't bother me showing against them one bit. I don't mind selling calves to them. Airing is really not that big of a deal in my educated opinion, as opposed to some of the other stuff that goes on. I'd love to see some enforcement to eliminate calves living several hundred miles from the kids that own them.
Not that anyone would believe it, but its not nearly as cruel to the animal as many other common COMMERCIAL procedures - dehorning, castrating, etc. Do you really think you can perform a horribly painful procedure on an animal and it even begin to be able to be showed by a little kid? I'll guarantee you a close foot trimming, pulling a hundred pounds off one, and especially cosmetic dehorning hurts them much, much worse. And like other types of these issues I've commented on in the past, the benefits are very marginal at best, especially with all of the fat supplements we now have at our disposal. It's an artifact of an earlier time that really isn't necessary anymore. We have better tools now that do the job much better - "legally".
As an exhibitor or a parent, your job or role isn't as the police. If you really think something happened improper, tell the show officials before the show. But that's not how these things happen is it? Nobody ever turns in the 4th place calves either do they? In my opinion, third party protests should be impossible after a show is over. Most of these cases are based on jealousy and sore losers - which is as bad or worse than the act the supposed cheaters committed in the first place. The bi***ing and moaning at shows ruins things for everone - ESPECIALLY the program as a whole which we all supposedly care so much about.
What really has raised my dander about this topic are the comments about the "40 year old 4-Hers". Would you rather have kids whose parents don't help them or teach them? I've seen very, very few parents cross lines in 4-H/FFA remotely close to what you sometimes see with the overly zealous "sports parent". This term gets thrown around by people who themselves weren't raised in the programs and again, are jealous that their kids can't win in whatever competition they are in. I really appreciate leaders that are willing to help even when they don't still have kids in the program, but those folks sure shouldn't be throwing that term around. Do a lot of us push our kids, sometimes hard? You bet. It's no different than the parents that push their kids to do homework, or just plain work on the farm or ranch. That's a lot better than the alternative.
