She may have felt like she was alone (maybe she didn't see the other girls) or that the easier option was to just say that it wasn't her until she saw that the other women weren't going to stand for this type of harassment and violation of privacy so now she wants to stand with them and make sure this person is put away for a long time.
So she is a coward and a liar?
why not "own that **** like beyonce" ala dylan sprouse
