Casey Anthony's lawyer tongue-tied when asked whether she'd let client baby-sit

This Casey Anthony defense lawyer may be crafty, but she ain't crazy.

Dorothy Clay Sims became tongue-tied when asked point-blank if she would let Anthony -- acquitted of killing her toddler daughter -- look after her own children.

"Would you let Casey baby-sit your kids? You say she's innocent," HLN interviewer Joy Behar asked Wednesday in a video that went viral.

Sims, a humble Social Security disability attorney in Ocala, Fla., before the sensational murder trial, appeared shocked.

Sims, who bonded with Anthony during the trial and gave her supportive hugs, couldn't answer.

Finally, she blurted out, "I feel the Casey Anthony I knew, I felt very comfortable with her."

Sims didn't return calls from The Post.
