It was a very Durbin-esque apology. Essentially: I apologize if you were offended, but I’m not sorry for what I said.
In fact, if you read this piece that discusses the ‘apology’ no where does she actually apologize for expressing her views at the funeral:
Knoll said that Sgt. Goodrich’s military service “was beyond the call of duty. If my regard for his family’s grief was seen another way, it is thoroughly regrettable. The fact that you have been offended deserves and receives my most profound apology.”
I guess that is the best we can hope for in terms of sincerity. As long as the family of Marine Staff Sgt. Joseph Goodrich is content with it, I will be too.
