I fully agree with you - more investigation and more heat on Jack has multiple benefits. Firstly she hopefully gets brought to justice, secondly the negative coverage does seem to be slowing her scam down, and thirdly, all the twisting & turning to try and deflect will keep her busy and under constant pressure, meaning she's got less time to spend building more false narratives and layers to the grift. It's all good in my book.
The ultimate goal as far as I'm concerned is to stop Jack ripping people off, bring her to justice and as an added bonus, if she's disgraced and shamed so publicly that it warns others from trying the same or similar, then great
