I tend to prefer rifles to shotguns, though I can use a shotty if I have to. This is a matter which I think calls for scalpels rather than broadaxes. Your mileage may vary.
As with all these scandals, the truth will keep "evolving" as long as it is sticking to someone. IMO, that is why it is important to clearly know where the truth ends and partisan fantasy begins. Most of the people directly involved in this don't even know what an IM is, let alone know that any goofball with Notepad could manufacture the "evidence" being used here.
In the end, after the election most likely, I imagine we will learn that Foley is indeed a scumbag, but, a lot of what is being bandied about by ABC as evidence has in fact been manufactured or altered.
