That's interesting considering the US had the same rate in 2007 and we have treat our criminals completely different. This would lead me to believe treating criminals like people isn't the key to successful punishment and eventual rehabilitation.
"During 2007, a total of 1,180,469 persons on parole were at-risk of reincarceration. This includes persons under parole supervision on January 1 or those entering parole during the year. Of these parolees, about 16% were returned to incarceration in 2007."
