GMS, forget about registration officers, focus how to train you polling agents. This applied to all opps polling agents. My friend a civil servant who served as a Counting Assistant in the last GE told me that the PAP's polling agents are very aggressive. They fought for every ballot paper that was in adjudication - as they were being trained - as it seems to be, unlike opps polling agents who are blur blur. Can't blame cos they were not trained. If one unable to identify which ballot paper is justified or spolit, or to their advantage, that's it. This is very important when the vote count is very near for both camps.
