Sadly I doubt jail would actually change her in any way, it'll be a few months locked up and she'll be queen of the wing- she could come out more arrogant than she came in.
Also, a stint in jail could look less likely thanks to the previous goverment's suspension of prison sentences that are less than a year, HMP's overcrowding crisis where it looks like even rapists might get released and the anti-prison, pro-rehabilitation philosophy of the new prison's minister.
