Do you think Kathy Griffin should just have apologized for her stunt and let it go?

By now, most everyone has heard about the comedian Kathy Griffin posting a picture of her holding a bloody head/mask of Trump. At first she apologized but now seems to be blaming the Trump family for “bullying” her.

I am not a Trump supporter, but I feel, in this case, he really did not bully her. He just said that it really bothered his family, especially his 11 year old son. She is now saying she will do even more Trump jokes.
Do you feel that she is right, that she has free speech and shouldn’t be called out for this, or is she in the wrong and should just shut the hell up?
