Back when the constitution was written, evidence was hard to find after a trial concluded that somehow warranted another trial. Nowadays, technology is all the range, and it is very possible that new evidence could be found that totally changes the original outcome. This is why double jeopardy should be elimated and people should be allowed to try cases twice.
Just how long could the average citizen pay expensive attorney fees? The government can outlast any citizen and absolutely destroy a person’s life and bank account for as many decades as they would want. If you get rid of double jeopardy you must also do away with the right to a speedy trial.
I think that the double jeopardy rule should stand. If a person has already been tried for a crime and gone through a trial that was found to be fair, he or she should not have to go through another trial. Also, the Fifth Amendment states that this is correct. We would have to change the amendment in the United States to eliminate double jeopardy and I do not think that is right because our country was founded of principles of fairness and justice.
