Far far more effective is lying by implication. This happens almost all the time. The article is written in such a way as to imply something is true; for example talking in such a way that said thing is obviously true and everyone knows it, when in fact it isn't true at all. This allows them to make the reader think something is true without lying, and often without even having the reader question it, and it allows the media to not even have to try to supply evidence at all.

Why don't we make a law around it? I'm tired of politicians weaseling themselves out of difficult situations by saying "oh, I forgot about that". It's your job to bring important, relevant information to the table, damn it.
