Nancy Grace ignited a firestorm of criticism by implying that Whitney Houston's death was a homicide. Despite pressure to apologize, the HLN legal pundit has not admitted she was wrong to say that.

I'd like to know who was around her, who, if anyone gave her drugs, following alcohol and drugs, and who let her slip, or pushed her, underneath that water? Grace said Tuesday on CNN, HLN's sister network . Apparently no signs of force or trauma to the body. Who let Whitney Houston go under her water?

CNN distanced themselves from the comment, with CNN's Don Lemon saying This is not CNN's reporting. We don't know that to be true. Whoopi Goldberg blasted Grace and said she should know better. And while being questioned by ABC News legal analyst Dan Abrams on Good Morning America on Thursday, she refused to admit it was wrong that she wildly speculated.

Grace has made a name for herself with her stinging opinions on famous crime cases and for making it to week 8 on Dancing with The Stars. The former prosecutor from Atlanta--who got into the business after her college fiance was killed in a mugging--rarely believes defendants are innocent. Below is a list of some of her harshest and most controversial quotes.

Casey Anthony Case

As the defense sits by, and after their champagne toast, after that not-guilty verdict, somewhere out there, the devil is dancing tonight.

 --Nancy Grace in July 2011, when Tot Mom Casey Anthony was found not guilty of murdering two-year-old daughter Caylee.

Amanda Knox Case

I was very disturbed, because I think it is a huge miscarriage of justice. I believe that while Amanda Knox did not wield the knife herself, I think that she was there, with her boyfriend, and that he did the deed, and that she egged him on. That's what I think happened.

--Nancy Grace to Access Hollywood in Oct. 2011 on Amanda Knox, the American study abroad student who was acquitted of murdering her roommate in Italy.

Michael Jackson's Death

[Conrad Murray] is still milking Michael Jackson like a cow. And I hope the judge takes that into account come sentencing time.

Nancy Grace to Extra in Nov. 2011 about Dr. Conrad Murray, who was later found guilty of giving the pop legend a lethal amount of drugs and sentenced to four years in prison.

Duke Lacrosse Team Rape Case

I'm so glad they didn't miss a lacrosse game over a little thing like gang rape!

--Nancy Grace in March 2006 about three Duke University Lacrosse students accused of raping a young woman. All three students were found to be innocent.

Melinda Duckett Suicide

If anything, I would suggest that guilt made her commit suicide. To suggest that a 15 or 20 minute interview can cause someone to commit suicide is focusing on the wrong thing.

--Nancy Grace on Good Morning America in Sept. 2006 on her interview with Melinda Duckett, a mother of missing 2-year-old. Melinda had committed suicide shortly before her interview with Nancy Grace aired on television her family sued Grace for wrongful death berating Duckett too much. The lawsuit was settled in 2010 and the family apologized to Grace and HLN.
