Where do you get all these facts I would like to know. You do seem to be informed. A federal prosecution is a total fuck story. IF, and it's a big "IF" he has done other illegal things and not been prosecuted, that are on record, or in his "minor" record, then sure a state probation charge would be in order. Something (the state charge) if he gets his head out of his ass, he can have expunged later in life. Now IF these things(allegations) are not charges, or just "suspicions", or what people have "seen/heard" then they are worthless, and bare absolutely NO relevance to this charge. Police and prosecutors DO use "Well, we are pretty sure he/she did this, or knows some thing about something we want to know about" so lets fuck them, as hard as we legally can! You cannot "think or believe" something happened, when prosecutors do this it's illegal, immoral and disgusting. You have to have a conviction, for a criminal history, period.  Federal is for life, without a pardon!
