Gerald,
In Ketchikan we have the Ketchikan Correctional Center.
Correctional Centers around the state at any given time might be people there who are convicted felons, people waiting for trial or sentencing. In K-town our CC serves all of the above plus misdemeanors.
I have been inside an adult Correctional Center on a weekly basis years ago to make weekly presentations on topics related to life skills.
My mother worked there ( no connection with my program), at a different time then me, as the "teacher" offering  adult education for inmates. She helped them with  classes for GED's, administered tests, helped inmates who were working on higher education degrees. 
 I have had dealing with murders, rapists and child abusers other a then at Correctional Center.
Yes, I have ! 
 Not only in court but personal "encounters", some personal relationships and correspondence with convicted murderers.
I have a family member convicted of murder + worked with a man who ended up killing his toddler.
