Modern comparisons show that murder rates are higher in death penalty states then in non-death penalty states. The most often used argument in support of capital punishment is that the threat of death deters crime more effectively than jail.

People get very upset and kill other individuals who they know.
Also many murders th at take place revolve around the drug trade Another popular argument for capital punishment is that if more executions occur, the death penalty will work to deter crime. Only a small proportion of first-degree murderers is sentenced to death, and even fewer are executed. That is because of the l engthy appeals process that occurs in death penalty cases. This considerable delay in carrying out the punishment is unavoidable. The only way to reduce the delays and costs of the death penalty is by disregarding the rights of American citizens.
