The problem most western countries like Australia have is that prisoners have rights. Not only do we have to provide them with food and water, but we have to provide them with TVs, gyms, exercise yards, libraries, reading materials, etc. That's basically why being sent to prison is considered as a holiday for a lot of criminals. None of them are afraid of the prison system.

What we should do is take all their rights away (as they have done to their victims). Prisons should consist of nothing more than a 6 foot x 4 foot room with a mattress and toilet and that's it, a small "cat door" at the bottom to slide in a cheese sandwich and a bottle of water. And that's where you stay for the term of your imprisonment. No contact with any other prisoners, that way it eliminates the drug problem as well as an older prisoner teaching new recruits. It would also stop puny little guys going in beefing up on steroids and gym workouts and coming out testorine fueled gorillas itching to kill or rape someone.

It would cost the government (us as taxpayers) less as you'd have less need of guards. It would also put fear back into going to prison to most of the criminals knowing that they're going into solitary.

And I'm not joking, I'd seriously do this even to juveniles.
