Interesting to watch this thread develop. The point behind the point of my original post was that I think there is a problem with some laws that are written in a way that nobody (players, managers, referees, supporters) wants to see them enforced. Not hard to sort with a rewrite. So IMHO :
1. Gk parry law. Change it so GK can pick up from any parry, deliberate or otherwise (which puts it in line with the general principle we judge what happens rather than guessing intent), provided it is part of the same action. I.e. No dribbling to edge of box then picking up
2. Ditch the 6 second nonsense and bring it in line with judgement we apply on excessive time wasting taking a throw, free kick, etc. This is what happens in the real world anyway
3. GK moving at penalty kick. This is a harder one. Law already includes the word 'blatantly', which is probably the best we can do. Alternative is to go back to black and white no movement before the kick is taken, but that was never applied either.
By the way, at the same time I'd remove the nonsense about colour of stocking tape. Causes hassle for no practical purpose and a complete nonsense with the new style boots that come up over the ankle. Twice now I've had to tell a player to remove an innocuous piece of tape you could hardly see from more than 5 yards away whilst his mate has a big black band around his ankle that are part of his shiny new nike mercurials or similar.
