She can hide from the public -- but not her conscience.

Casey Anthony will change her name and don disguises to evade an outraged public when she's sprung from an Orlando jailhouse Sunday, after a jury shockingly acquitted her last week of murdering her 2-year-old daughter.

She even considered plastic surgery, a source close to her defense team said.

"There even have been discussions about cosmetic surgery, but Casey has rejected that," the source told the Chicago Sun-Times.

One issue is that the Casey, 25 -- who has received death threats since the unexpected verdict -- has been in jail for three years, and doesn't comprehend how loathsome she's become.

"Casey really does not completely understand the depth of hatred out there," the source said.

Upon her release, she'll assume a pseudonym "almost as if she was living in a witness protection-like program," the source said.
