Correction: The developer has not been charged... yet.
If you dig into someone's past, you can probably find something, or make it look like there's something. Pay informants. Frame people for other crimes. Etc.
When a justice department doesn't believe in the laws they're supposed to uphold, they don't have to follow their own rules. They can send people through the judicial wringer by merely filing a complaint against them.
That in itself is a punishment.
