Absolutely do not accept a plea bargain of any kind. I was tricked 8 years ago into something similar! His life will never be the same. He needs to be aggressive in squashing false allegations.
1. Consider filing a defamation case against the false accuser.
2. Get a polygraph done. Get a psyche eval done.
3. Get and keep your media conversations going. If he is innocent, then make everything public. Talk to everybody who will listen.
Let me know if you need help.
