Capital punishment may also have a reverse effect contradictory to its whole purpose. Jury members know the possibility of their defendant being put to death is real, and therefore may be less likely to convict. It's easy to say to the government that the death penalty is OK, but once someone's life is in your hands, your views may change. In addition to all of this, innocent people get killed because of many false judgements. The penalty of lifetime incarceration can be withdrawn if one is proven innocent.
Death is permanent.
What's more, new legislation has been implemented in Florida which reduces inmates on Death Row's appeal opportunities, which will result in swifter executions. Thus, there is a greater possibility of killing innocent people. Great discrimination is involved in the execution system as well. And referring to a Philadelphia study, after controlling for levels of crime severity and the defendant's criminal background, death sentences were 38 percent higher for African-Americans. In the same way, prejudice is shown towards the victims of crimes as well.
