She has certainly received very bad legal advice by admitting anything to the reporter, she has indeed a very good case to claim self defence but not if she tells everybody she is guilty before she is even charged!
She’s on a quest. I like her:’)
The big problem is that criminals have a big advantage over the law-abiding, due to their intimate familiarity with the details of how the criminal-justice system works. Long-time criminals generally know better than to admit to anything, and know that the first one to make a police complaint is generally the one in control of the situation.
