@livereal - There are problems in all countries in terms of penal systems and prisons, but I think it is widely accepted that some countries are far more advanced than others. It is complicated by the variability of resources and accessibility throughout the world. For instance, many poorer countries and those with very limited resources can’t hold as many prisoners. In terms of the prison buildings themselves, there are usually not as many and the ones that do exist can be very deteriorated. For this reason, these types of countries often use forms of punishment and incarceration that more developed countries would consider archaic.
Of course, this also lends itself to the belief that more developed countries are at least better in terms of prison systems than less developed ones. This is problematic, as there is still much progress and development necessary. As the article states, many countries are not operating in a way that promotes rehabilitation. Prison reform could seriously help societies beyond the prisoners themselves, as it would probably decrease crime and offer real solutions to problems of crime and criminality.
