You have to remember though that they're a political party - they say what it is politically advantageous for them to say, or what they can spin it to look like. There is no black and white nor right or wrong in their eyes, only angles, spin and PR. How true they are being at any given time depends only on how they can use it to their advantage. If it is politically advantageous to tell the truth, they will do so, if it is politically advantageous to distract from, cover up or lie about, they they will equally do so. You can't trust them, all you can trust is if their angle currently aligns with your goals. This is how dishonest bills get piggybacked through while everyone is looking in the wrong direction, this is why political arrests are made, this is why the Government backtracks on Whistleblower protections and they condemn countries that use torture to achieve their ends... until they themselves are caught doing it, only to throw their hands up and say "Hey, it was necessary!" You can't have your cake and eat it too. Life isn't black and white, it's grey. Nobody is innocent, everyone has capability of good and evil (if you choose to look at it that way). But when you can only trust someone as far as their political agenda, how do you know when to trust them and when not to? I agree with your point though of not automatically believing or disbelieving in what they have to say, you have to look at whether it is more politically advantageous to be truthful or deceitful... but with more and more information coming out that shows the level of their deceit, you have to wonder if anything they say is true or if it's all spun for political advantage.
