Four possibilities:
A. Innocent and found Innocent?
B. Innocent but found guilty?
C. Guilty but found innocent?
D. Guilty and found guilty?

OUTCOMES as far as reforming system:

A. Will he still naively believe that B doesn't happen and that
he doesn't need to go back to the legislature and fix broken process?

Or will he realize how crappy the system works and realize how close
he came to being a prison bride even though he was innocent?

B. Prison. Possibility for enlightened repair of system is small.
Career as legislator after prison is doubtful.

C. He'd probably never want to mention it again in ANY way, and
would probably seek no reform whatsoever.

D. Prison. He'll probably only do 2 years and become your neighbor.

Seems like people "enlightened" by direct experience
are unlikely to work for correction. Even if he wins in
court, he may just think that proves the system works.
