So, suspended Labour MP Taito Phillip Field is now refusing to be interviewed by the police. National is of course outraged, and trying to blame Helen Clark for it (of course. As opposition, they'd blame the government for the weather if they thought it would stick). Meanwhile, since it has so obviously slipped John Key's mind, I thought I'd remind people again: we have a right to silence in this country, and no-one, no matter who they are or what they are accused of, has to talk to the police. As the subject of a criminal investigation, Field is merely exercising that right - a right which exists to protect people from abuses of power and society from a police force which forces "confessions" - and he has every right to do so.
Meanwhile, I'm sure that Key's statement that "If Mr Field has nothing to hide, he would have no problem speaking to the police" will be very useful to Field's lawyer if he is every prosecuted, in arguing that he cannot possibly receive a fair trial due to widespread pronouncements from authority figures and assumptions about his guilt.
From what we've already seen about Field, we can conclude that he's not fit to be in Parliament. But it would be better for politicians to stand back and let the police conduct their investigation, rather than wading in and potentially undermining both it, and our human rights.
