That doesn't appear to be the case here. If you read the last linked article, it looks like the prosecutor was operating under guidelines established by a former Attorney General. The current Acting AG changed the guidelines.Just FYI, all DAs will go for the throat at first. They place the harshest of all charges on the table and then they can if they choose to, negotiate down.
I think the prosecutor got what they wanted and the defendant got a lessor punishment.
