Apologies Then and Now
I remember Dr. Laura saying a real apology has three parts - remorse, repentence, and restitution. You're truly sorry you did it, you resolve to not do it again, and you do what you can to set things right. Dennis Prager would add a clarifying prologue, a statement up front of what you did wrong that you are now apologizing for.
Senator Durbin's apology embraced none of this. He only wished we could understand him better, like his journalist friends do. Of course, if a teenage child of one of those journalists tried to float an apology like that, they'd be grounded for a week.
