Nancy Grace – whose coverage
of the Casey Anthony murder trial
received nearly as much attention as the case itself – says her focus now is to put the backlash behind her.
"I know that a lot of people hate me and say rotten things about me," the HLN network legal commentator, 51, tells The Hollywood Reporter
. "The only thing I can do is keep working."
Though she expressed outrage
over Casey Anthony's acquittal, Grace – a former prosecutor – says she still has faith in the American legal system.
"It's a very hard thing to digest when your justice system fails you, but … you cannot stop believing in it because it is the best system in the world," she says. "The system can fail, but that's all we have."
With Anthony set to be released
on July 17, Grace says she will now devote her attention to other cases.
"We've covered literally hundreds of missing people, missing children, unsolved homicides since Caylee went missing," she says. "It's just hard when you're so emotionally invested in a particular case. … But like every good trial lawyer, what you have to do is set aside those emotions and that investment, because there are other cases that need you. So I'm going to pick up the next file and go on to the next missing person or missing child or unsolved homicide."
