Now that there is probable cause and the court can't make a decision, should they search Luke and Kesha for evidence such as emails, photos, messages, etc. of the rape? Who's willing to hack Luke?

...and how will Kesha explain how she obtained this newly found evidence?

No one's willing to go to jail for the woman.

check wikileaks, specifically the sony leak from here and see is there is any evidence:

and
https://wikileaks.org/sony/emails/emailid/98818

you can't provide evidence that was get illigally

Annalise Keating does it all the time though. Where's Oliver at?
