Indeed your scenario certainly would happen, no argument at all there. Mine ,however could also take place, in that the photo would be available for further examination, by people with a less slanted view than other competitors, which would balance things.
In your area the handling may not be having any real effect, down here the story is different, the two major offenders work as a team,one distracts the steward while the other plays sandcastles! And handling is not all they get up to,plot markers have been known to take a walk for example and their efforts do have a bearing on results, and I have heard the elder being abusive to a judge who had marked him down at a previous match.
Yorkshire Disease now seeming to pale Into insignificance. New title required whether it be mainly confined to an area south of the M4 or more wide ranging to cover an area south of the M6. Comments please but for starters Southern Counties Disease.
No excuse whatsoever for abusing either officials or fellow competitors but what your post does put under the spotlight is the bad feeling shopping fellow competitors causes. There is - made quite clear in the penalty deductions - an item for abuse of officials or fellow competitors. In real terms then shopping fellow competitors could be classed as abuse - definitely an abuse of the officials by insinuating they are not doing their job correctly. Again - an issue easily resolved. 20 points off for the first offence. Whether or not to disqualify for the second offence being up to the organisers. If that’s not sufficient then send their entry back the following year.
One of the more serious consequences of taking the law into ones own hands is that some people tend to jump on the bandwagon in order to boost their own score/position. Pointing out other competitors mistakes to judges is another act of low cunning that needs to be addressed. Some are veritable masters at it.
