Yeah unless, well you haven't read the comics but haven't I told you about her connection with Mystique and Xavier and stuff? She literally takes away the memories so she can't put them back in, she is stuck with them and the culprit no longer has that memory, it would be useful to get information but sifting through a bad guys head will bring unwanted memories as well. All from skin contact! That is why her gloves come in handy!
