Don't. They take forever as they have only so few lawyers and they're all backlogged for months. They're also not equipped for this kind of thing. Their lawyers focus more on civil suits, not criminal..
(That said, I can see another problem in cases such as this: what if some of the "volunteering lawyers" are set by the government?).
My IANAL guess is that they would still be bound by client/attorney privilege, and they'd be committing a crime if they violated that.
