Obama does not apologize to Crowley but he comes close.

After speaking with Crowley on the phone the President said " I want to make clear that 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."

Earlier the Cambridge police union demanded an apology from Obama:

"I think the president should make an apology to all law enforcement personnel throughout the entire country who took offense to this," Stephen Killion, the president of the Cambridge Police Patrol Officer's Assn, said at a news conference in Cambridge. He was joined by Crowley and local and state union officials.

Not sure why adding "I am sorry" is so difficult for some people - Obama should have said those 3 words. But I commend him for calling Crowley and acknowledging his screw up.
