Prior knowledge about prison sentencings

So I can think of three big issues involving prison sentencing, they are the death sentence, sentencing children, and minor drug offenses. The death penalty is obviously controversial because it is killing another person. Many people think that if the person crimes are bad enough then they should lose their life. Others believe that it is wrong to kill others and that life in prison is just as harsh. With child sentencing many argue that children's brains are still developing and that I'd that some aren't old enough to understand their crime then they shouldn't be sentenced to prison but instead a more passive approaches like therapy. Finally with most sentencing's the person being incarcerated had a minor offense which many thing is unfair but others believe if they broke the law then it is a fair punishment. All three of these are potential final paper ideas.
