If people want to help Aaron, I'd recommend a political strategy as well as a legal one. I'm not a lawyer and certainly no expert on this case, but my sense is that there is something political going on or one of the prosecutors sees this as a big career boost. For someone without a criminal background like Aaron it would seem very much out of the norm to continue escalating the charges as they've done, rather than move toward a plea bargain.

These prosecutors work for the Obama Administration, and ultimately the President. The President has certainly courted the tech/internet vote, and I think some internet activism in this case is worth a shot. But it would need to be done basically right now (i.e. before the election). Are the prosecutors going to drop the charges? No. But some political pressure could improve whatever the terms of a plea deal are.

Disclosure: Aaron and I briefly worked at the same non-profit organization many years ago. But we were essentially in different departments, so while we met once or twice I wouldn't say I know him personally.
