Not these days, when lying and manipulation of the media has become a sophisticated art form. In my experience its not so complicated, there is usually one party telling the truth and the other spinning a lie.As with most things in life, the truth probably lies somewhere in the middle of both sides version of events.
True, as outsiders it can be hard to know the truth, so the simple thing is to say 'Oh they are maybe both a bit right'. In which case the lie has prevailed, at least to that extent.
