Umpiring lunacy, why does the AFL allow it?

Koschitzke smashes Malceski in a "head" high crude tackle, "3 umpires don't see it", then moments later he is rewarded a free for a 'finger nail' touch to the back. The free results in a goal, the first of 3 bringing the Saints into the game and puttinfg them in front by a margin the Swans could not later make up, costing them the game by 8 pts. Sadly AFL umpiring incompetence is so obvious its a joke, but we can't laugh, because the reality is its "totally ruining the game", commentators know it, see it, but obviously can't do their job and COMMENT on it. Its seriously time these whistle drongoes, give up their 9 to 5 day jobs, and become "full time" professionals like the players. The job has got to be done right. The Saints open their account due to umpire freebies, its lunacy and it sickens me. I hate having the thought through umpiring incompetence,that the AFL has away to MANipulate the result of games .
