Some of the letters are simple thank yous to the center for sending copies of its magazinePrison Legal News, while others are first-hand correspondences, detailing allegations of abuse, physical violence, and deplorable living conditions.

"We have been getting hundreds of letters from Florida prisons on a weekly basis since Human Rights Defense Center went to trial last month against the whole Florida Department of Corrections having a blanket ban on our magazine," says Special Projects Coordinator Panagioti Tsolkas.

While details of Florida's unsavory prison conditions have been chronicled since the days of "Old Sparky," in the last few years alone, there's been extra scrutiny on deadly abuse in Florida prisons. It's been chronicled at length in a Miami Herald investigation - including the story of Darren Rainey, a 50-year-old mentally ill inmate at the Dade Correctional Institution who died after he was locked in a scalding hot shower for more than an hour by prison guards as punishment for defecating in his cell. There was also the story of Randall Jordan-Aparo, a 27-year-old man being held on credit card fraud charges who was found lifeless in his 13-by-8 cell after guards at the Franklin Correctional Facility fired nine blasts of noxious gas into the confined space.

These accounts among countless others have helped to boost community involvement in raising awareness about what is going on behind prison walls.

"Since the event we did on Human Rights Day last December, we've had a steady flow of volunteers who come and help us with our outreach efforts to prisoners all across the US, well as help with typing hand-written submissions we receive to the PLN magazine or website. We have been working closely with the Prison Books project to provide opportunities for people to get involved with prisoner solidarity work in a practical and meaningful way," Tsolkas says.

Saturday, there is one more way to get involved when a handful of anti-prison groups gather at Outspokin community space for a night of acoustic music and spoken word to benefit the Human Rights Center's Prison Ecology Project, which aims to connect the links between mass incarceration and environmental degradation and the South Florida Prison Book Project which helps promote literacy for the imprisoned.
