"And I could have calibrated those words differently...."

Quote from President Obama:  Because this has been ratcheting up and I obviously helped to contribute ratcheting it up, I wanted to make clear in my choice of words I think I unfortunately gave an impression that I was maligning the Cambridge Police Department or Sgt. Crowley specifically. And I could have calibrated those words differently.

 

What the hell is that supposed to mean?  It means that I never have say I am sorry or said a wrong thing.  I can say my words were miscalibrated.  Thanks Oprah!
