I completely agree - but the fact is that they simply don't do it. What happened to the 'respect' thing when only the captain was allowed to approach the ref? It just got dropped. The experiment when dissent at a free kick saw it moved forwards 10 yards? Not implemented. We all moan about refs (with justification a lot of the time) but I think they do have a difficult job: maybe it is time to actually have proper, professional, full-time referees? Then the game might be able to recruit some ex pro footballers into the job - they would certainly be more aware of what's going on than some of the current crop?
