The public eye isn't who she is trying to please or who she is concerned about. Her lawyer clearly stated that she wants her daughter back (and then he said something like "and Sherin") so he is likely working hard behind the scenes with CPS and the family courts trying to get visitation setup in the interim as they wait for her to be given custody back.
Whether she will ever get custody again or not will depend on what LE finds but at this point we are to assume LE still doesn't expect to press charges against her and that her child was taken because of the circumstances surrounding Sherin's disappearance.
He could be a really bad lawyer, or he could be a great family lawyer and fighting hard for her behind the scenes. Does anyone know if he is also a criminal lawyer or what he specializes in? In my area there are family lawyers, criminal lawyers and some who do both. I would assume he does both given the investigation, but if he is a criminal lawyer only that could lead to some speculation.
ETA: I do think if she ever does begin to speak that she should consider someone who deals with PR because the way her lawyer worded some things, like her "mourning" is very conflicting and gives an impression of guilt. However, regardless of how much she talks or stays silent, people will always tear her apart.
