I don't support capital punishment anymore because I believe that a cold blooded murderer, with no just cause (self defence for example, which would likely be classed as manslaughter anyway, and not murder, depending) deserves to be punished, and killing the criminal could be an easy way out.
Prisons should have isolation cells, no pool tables, no TVs, or entertainment, they should have facilities to learn something useful for when they get out, and they certainly shouldn't get paid anything meaningful if they work in prison, they should have enough money when they get out so that if they havent got any housing, they could afford to rent a place for a few months, which would give them some time to find a job.
I'd support corporal punishment aswell, like lashings for extra punishment, many of you might disagree with me and claim that "they have human rights too" -well they should have thought about that before they commited their atrocity. Abuse as a child is no good reason to take it out on someone who has done nothing wrong against you, the person should seek help when the incident happens, not take it out on some unsuspecting victim, theres a name for that sort of thing, its called scapegoating. People who have a serious mental deficiancy should be treated differently though.
