Hi.
Here are some sources worth checking out:

www.prisonplanet.com/articles/september2005/150905nwoshowcase.htm
www.corrections.state.la.us/Katrina.htm
www.aclu.org/Prisons/Prisons.cfm?ID=19225&c=121
www.prisonsfoundation.org/news.html
There seems to be a lot more on police brutality than prison workers.
Please let me know if these are not sufficient or if the links do not work.
