For Constitution Day he spoke at Hillsdale College:

The conclusion to his beautifully sane speech:

QuoteIn short, it is important for prosecutors at the Department of Justice to understand that their mission — above all others — is to do justice.  That means following the letter of the law, and the spirit of fairness.  Sometimes that will mean investing months or years in an investigation and then concluding it without criminal charges.  Other times it will mean aggressively prosecuting a person through trial and then recommending a lenient sentence, perhaps even one with no incarceration. 
Our job is to be just as dogged in preventing injustice as we are in pursuing wrongdoing.  On this score, as on many, Justice Jackson said it best: 
"The qualities of a good prosecutor are as elusive and as impossible to define as those which mark a gentleman.  And those who need to be told would not understand it anyway.  A sensitiveness to fair play and sportsmanship is perhaps the best protection against the abuse of power, and the citizen's safety lies in the prosecutor who tempers zeal with human kindness, who seeks truth and not victims, who serves the law and not factional purposes, and who approaches his task with humility."

If Bill Barr has anything to say or do with law, most of the Democrats will hate him. The lawless ones have no belief in the law, no respect for the law and no willingness to adhere to it.
