One News last night had new allegations against Taito Philip Field - this time that he had helped another Thai overstayer gain residency in exchange for painting several houses. Like the first case, this is dodgy as hell, and should be fully investigated. There's nothing wrong with helping overstayers to normalise their status (and in fact, I think its a Good Thing, especially where they have skills in short supply) - but asking for or accepting a quid pro quo in exchange is corruption, is illegal, and ought to be prosecuted.
As with the previous case, Field has issued a flurry of statements, including from the person he helped. But given that the statements from the Cole family appear to have been extracted by bullying and standover tactics, I'm not sure how far they can be trusted. Something else for Dr Ingram to investigate, I think.
