It's not that she hasn't been a judge.  Actually, I kind of like that about her.  It's not that she's got some gossamer-thin connection to Goldman Sachs.  I'm concerned about her deference to executive power, and what that may well portend for important issues of personal liberty and police power.  I haven't found anything that speaks directly to her thoughts on Miranda, search and seizure, confrontation, etc.  Anyone know anything regarding her stance on these issues concerning liberty?
