Every year the gates of Louisiana State Penitentiary, also known as Angola Prison, open to the public for an increasingly popular rodeo show.

The participants are some of the most dangerous prisoners in the US, and most are black, from urban backgrounds and have no training.

But for a few days a year, the inmates get to see their families and have a taste of freedom - factors the organisers say can help rehabilitate offenders.
