Yeah. The statement does have a point regarding some folk not knowing the laws, or choosing to ignore them when it suits. Ex players banging on about 'no malice' or 'accidental' is embarrassing. When they are being paid to give opinions, surely it's not to much to ask they are informed opinions.
Saturday's decision is just as embarrassing. As you say, according to the current laws of the game, there was absolutely nothing wrong with that goal, so how can at least two paid, trained officials with the benefit of endless replays make such a pig's ear of it?
