After 17 years, I don't think I'd want to take my chances. Plus, compensation for wrongful imprisonment never seems to be too much anyway, and I don't know if anybody ever wins cases civil cases for such things. I suspect you'd have to prove that the prosecution acted with malicious intent, or something. What they will be able to do, hopefully, is sell their story to HBO for a hefty chunk of change.
Something that I've wondered is if The Man could use some bullshit victim's rights thing to prevent them from making money off of their story. I'm not sure what laws they have for that, or how the Alford plea would work in relation to it. Unfortunately, form what we've seen of the State there, it wouldn't surprise me for them to pull something like that.
