Essay on FOR the death penalty. Review and edit please?
So I’m writing an essay on FOR the death penalty. This is just the first draft of like not even two paragraphs. Please give me some tips/help? Keep in mind that I’m only in 8th grade.
Oh and btw, my teacher said we had to start with a sentence like I did. It’s lame, I know, but whatever.

Did you hear about that guy who murdered a whole family just because their tree hung over his fence?I think we should enforce the death penalty because of people in the world like him.

The U.S spends billions of dollars on housing prison inmates.It costs an average of $47,000 per year for just one prisoner.That’s about $1,880,000 for life if the person beings a life sentence at age 35 and lives to 75.

Wow, did know realize how short that is. Oh well. So do you think I’m doing okay so far?

Of course I wish you the best of luck on this essay. But the facts are different.

Costs, a surprise to many people:
Study after study has found that the death penalty is much more expensive than life in prison. The high costs of the death penalty are for the complicated legal process, with the largest costs at the pre-trial and trial stages. The point is to avoid executing innocent people. The tremendous expenses in a death penalty case apply whether or not the defendant is convicted, let alone sentenced to death.

Examples- trial costs (death penalty and non death penalty cases, California):

People v. Scott Peterson, Death Penalty Trial
$3.2 Million Total
People v. Rex Allen Krebs Death Penalty Trial
$2.8 Million Total
People v. Cary Stayner, Death Penalty Trial
$2.368 Million Total
People v. Robert Wigley, Non-Death Penalty Trial
$454,000 Total
This data is for cases where the best records have been kept.

Some factors:
• more pre-trial time will be needed to prepare: cases typically take a year to come to trial
• more pre-trial motions filed and answered
• more experts will be hired
• twice as many attorneys will be appointed for the defense, and a comparable team for the prosecution
• jurors must be individually quizzed on their views about the death penalty, and they are more likely to be sequestered
• two trials instead of one will be conducted: one for guilt and one for punishment
• the trial will be longer: a cost study at Duke University estimated that death penalty trials take 3 to 5 times longer than typical murder trials

The numbers vary from state to state, but they all point in the same direction.
