There was a salutary lesson on Tuesday for all those who believe technology should play a greater role in modern cricket.
There have been loud and sustained calls for the cameras and microphones to help the umpires rule on anything from leg-before decisions to bat-pad catches.
They'll help clear up any element of doubt, so the argument goes.
Well trying telling that to anyone who watched the fourth day of the first Test between Pakistan and England in Multan.
In the first over after lunch Pakistan's centurion Salman Butt ambled back for a third run as Paul Collingwood picked up the ball on the deep mid-wicket boundary.
A second or two later as the ball arrowed in to England 'keeper Geraint Jones it suddenly became obvious that Butt was struggling to make his ground.
The bails were off in a flash but it looked incredibly close, in short exactly the sort of situation on which TV replays would be able to give a definitive verdict.
After multiple viewings from numerous angles it finally appeared as if the stumps had been broken and Butt would be on his way back to the pavilion, but to general astonishment it was the green 'not out' light which flickered on.
I have to be honest and say that at that point I reckoned the decision was an awful one - so much so that I suggested it made a mockery of using the technology.
But a few hours later and after repeated replays and discussions, I have to hold up my hands and concede it was exactly the right decision.
The key are laws 28.1 and 28.1(b) which state:
The wicket is put down if a bail is completely removed from the top of the stumps, or a stump is struck out of the ground...
The disturbance of a bail, whether temporary or not, shall not constitute its complete removal from the top of the stumps...
A couple of angles clearly showed that the stumps had been pushed forward by Jones' gloves but it was impossible to say categorically that a bail had been removed in the split second before Butt's bat slid over the line.
Given which third umpire Asad Rauf made the correct and brave decision to give the benefit of the doubt to the batsman and rule it 'not out'.
The verdict could have turned the match - as it happened Butt was out fairly soon after as Pakistan collapsed - so the fact that it caused such controversy and polarised opinions is a real warning against extending the remit of the third umpire.
The system works as well as it possibly could at present - 99 times out of 100 we get a definitive answer to run out and stumping appeals - a markedly better ratio than we'd get by going with the two umpires on the field, however good they are.
This was simply the one out of 100 chance, the exception to the rule.
But imagine if we took the TV verdicts further - to rule on leg before for example?
It would lead to so many similar instances as this - where even with the help of the cameras we still couldn't agree on key decisions.
The third umpire would be regularly - and often unfairly - lambasted by TV commentators, supporters at the ground, and millions of TV viewers.
The game would also be slowed down as a result and the on-field umpires would lose a bit more of their authority.
Tuesday's incident should therefore serve as a useful reminder that the umpires have a better knowledge of the laws of the game than the majority of the watching public, commentators and even players.
The issue of whether the bail itself had to be removed wasn't even thrown into the melting pot until we searched for some sort of explanation as to why 'not out' had been the verdict.
And in another example earlier in the match, acting Pakistan skipper Younis Khan had questioned on-field umpire Billy Bowden's decision to call what looked a harsh wide against spinner Shoaib Malik.
But Bowden was absolutely spot-on - a recent change to the law means that if spinners use the rough outside the batsman's leg stump then that activates the one-day criteria on wides.
Indeed Bowden and his colleague Simon Taufel have been outstanding thoughout the course of the match.
When England last toured Pakistan there was plenty of controversy as the decisive third Test finished in near darkness in Karachi.
That won't happen in this game because Bowden and Taufel have set a clear precedent from day one as to when the light should be offered to the batsmen.
They've left the field at 4.41pm, 4.42pm, 4.42pm and 4.46pm (the extra few minutes on account of spinner Danish Kaneria bowling) on the first four days.
That's typical of the way they've handled the game and everything we've seen in the match suggests that the balance between their on-field authority and the use of technology is exactly right.
