Why would the judges, or the competing walkers, or their coaches, or their families know more about this issue than a 'hurler on the ditch' AAM poster?
Perhaps because they feel that important decisions about the sport should be made by people who know and understand the sport, rather than armchair experts armed with their Sky remote?
I would be equally vehement, on the assumption that you know nothing about fencing. If you know nothing about it, don't assume that having a Sky remote makes you an expert. Have some trust.
I find your repeated use of the "armchair" expert digs in this thread (and others too
) an attempt to undermine poster's credibility. Having trust, as you say, is one thing, but it's also prudent to be sceptical. If enough people disagree with something and voice their disagreement, changes can and usual will prevail. All you have to look at is the trade union movement!
In relation to sport, obviously, athletes, coaches & referees know an aweful lot more about a sport than the average punter/fan. I don't think anyone would argue with this and I think at this stage we get your point. However, sport, in its nature is, by and large, totally dependant on the subjective opinion of the referee.
An exception here (recently) is in golf where Pagraig Harrington was disqualified from the Abu Dhabi Championship after a home viewer spotted PH replacing a ball incorrectly on the green. Another example in golf concerns Graeme McDowell

I guess the challenge regarding technology is how much of it to allow so as to increase fairness but also not adversely affect the flow of the game.
In the case of walking there is an interesting article here
http://www.nytimes.com/2012/08/11/s...alking-is-more-complicated-than-it-seems.html which details the issue of both feet off the ground as visible via freeze-frame photos. However, "Rule 230 of the I.A.A.F. rule book states that “racewalking is a progression of steps so taken that the walker makes contact with the ground so that no visible (to the human eye) loss of contact occurs.” “To the human eye” is the critical part because it underscores the subjective nature of judging the sport." So they have it covered for now. As this is a pretty minority sport and only gets noticed in the main every 4 years changing this rule may take some time, or may not change at all.
I don't think there is anything wrong with someone having an opinon about it though. For me, I think it is a deserved Olympic sport. I don't think the rules should be changed either
