Is this an attempt to spark some inane conspiracy theory?
A suggestion that Aaron's involvement as a 'source' made him a target of the government, so his suicide was not actually a suicide but rather a targeted attack?
That was my first reaction: -if- this were true, it would 'help' the DoJ 'explain' why the prosecution was so vigorous. (Tying Swartz to something they've spent years bad-jacketing.) A similar move is the claim he FOIA'd tapes of Manning in custody. Looks like the Big FUD Machine's running.
Mashable may be leaving the 'not suicide' conspiracy theory open but I don't think that is what Wikileaks are suggesting.
