Honestly, I think she *needs* jail time. She has, for whatever psychological reason, been pushing boundaries for a long time, and getting no response other than, "Well, *next* time we'll get serious! Believe it!"
Jail may actually give her time and impetus to get her life sorted out, as it has for a number of other celebrities - perhaps even give her the confidence that she can face adversity on her own, rather than insulated from it by all the trappings of celebrity.
