prison be a sign of the failure of our society . society fail in that it be unable to prevent the original crime while and then again and in lock up those criminal in a world of squalor and drug abuse and and violence and rule and in effect and by the criminal hierarchy whose delicate co operation with the authority be necessary to maintain any semblance of order . carandiru and base on the memoir of a prison doctor in brazil and be a fairly conventional prison movie and tell u the criminal story ( a tell to their medic ) of life both outside and inside the bar while but it still an absorbing tale and with moment of humanity flash through the hole in a very grim backdrop represent the end feel like overkill until you learn the sober statistic of the real event on which it be base . of course and the poverty of brazil undoubtedly contribute to the terrible nature of the ( now demolish ) carandiru while but this week the british government triumphantly announce it plan to build four new mega prison and another story it hard to see end well .
