As far as I can tell. The writing seems to indicate that.

Another quote from her same book furnished by fucking Glenn Beck, if you can stomach that source, with the bit about people convicted of murder:

When we moved in, I was told that using prison labor at the governor’s mansion was a longstanding tradition, which kept down costs, and I was assured that the inmates were carefully screened. I was also told the onetime murders were far the preferred security risks. The crimes of the convicted murderers who worked at the governor’s mansion usually involved a disagreement with someone they knew, often another young man in the neighborhood…

I saw and learned a lot as I got to know them better. We enforced rules strictly and sent back to prison any inmate who broke a rule. I discovered as I had been told I would, that we had far fewer disciplinary problems with inmates who were in for murder than with those who had committed property crimes. In fact, over the years we lived there, we became friendly with a few of them, African-American men in their thirties who had already served twelve to eighteen years of their sentences.
