A post on the above blog for 08/11 mentions a homeless man who had been to prison because of drugs, and because of the prison term, is having a problem finding a job. There is the danger that eventually he will become desparate and do something that lands him back in prison. Is this really in the best interest of our country? When will our country choose our common good over the satisfaction of punishing others?
