People change, especially after being punished for the mistake they made for 13 years. Chances are she would be less likely to engage in violence than the people you currently sit next to, because she has a personal understanding of the harsh punishment it would involve.
Edit: The downvotes that this comment is currently receiving actually illustrate the problems outlined in this thread. If you disagree with the idea that people can change, you will never hire someone with a criminal record, and you will perpetuate the problem. The unemployment rate among felons in the US less than 2 years after release is 31.6% [1]. The unemployment rate at the peak of the Great Depression was 24.9% [2]. It is always the Great Depression for the felon population, because of the incorrect belief that people can’t change. Among any population with unemployment this high, there will be a drastically higher crime rate.
