Think 2 - Capital Punishment

Is capital punishment the right thing to do or the wrong thing to do? 13,000 and more has been legally exectued since colonial times. There are alot of good outcomes from this. Capital punishment is also known as "the death penalty". When someone convicts a crime of murdering a person, should he be executed?  If he is then this will prevent other criminals from commiting any other homicide or murder cases.  Studies shown that 1 execution deterrs 18 murders in the future. Also prisons in many countries are over-crowded and under-funded, and this problem is made worse with a life sentence. Why should any taxpayer bear the cost of supporting a murderer for an entire lifetime?  Now here are the cons of capital punishment. Although capital punishment can cost more than a lifetime sentence.  Most capital cases from arrest to execution, can cost between 1$ million to 2$ million... pennies. A case resulting in life imprisonment can cost around $500,000. It's best to avoid the death penalty because there has been incident where the criminal was innocent.  About 23 innocent people were executed in the U.S.A in the 20th century. Defendants who are mentally incompentent will often answer "yes" to questions in the desire to please others. This can lead to false confessions.  Over 30 mentally retarted people have been executed in the U.S.A since 1976.  Are we suppose to show that killing is wrong if we are having them killed too?  They say that every human being is entitled a second chance. I don't know who "they" are, but they said it!
