I've had many conversations with people who are all for the death penalty, and some even think prisoners are far too well cared for in prison! All the prisons I've been in had a small 'hospital' with a trained nurse and a visiting doctor, and regular visits from a dentist. Their daily dinner was tasted by the governor to ensure it was edible. Heating was provided in the cells, and those inmates with hardly any clothes were given prison wear, including pyjamas.
Now, people who want offenders to be bumped off with the noose or a fatal injection, or locked up in dire conditions etc seem to me to be 'criminal' in their own way. Where is human compassion and understanding?
