To be fair, people get confused between the laws of the game and the way those laws are applied in England with the referee's interpretations. The laws of the game are there for everybody to read and, generally, are very sensible and "easy" to understand. "Easy" as in the context of a game we all understand reasonably well. The problem with referee's interpretations is that we have never seen them (have we?), so we don't know how the laws are being applied, other than getting a few generic comments at the start of every season, unless we try to guess them from watching the decisions made. So it's natural no-one has a bloody clue. Probably how they like it.
