Yes,she should do serious time...at least as much time as it takes to convince her to never,*ever* do anything that stupid again.And maybe even longer than that.But not life,particularly given she had a clean record before this.If she was an habitual criminal then life just might be fitting here.
Remember in the civilized world prison sentences are a lot like sports contracts, they sound a lot bigger than they are. Depending on which version of the life sentence they give her she could be eligible for parole anywhere from 7 years to 25. And that’s only if they hit her with the max, which with no previous record they probably won’t.
