I don't put my faith in a system that is biased towards the wealthy. Hence, why I don't support the death penalty.

DNA is not 100% landover, it can be contaminated, cops can lie and plant evidence, and more importantly those with the best lawyers can get off regardless of evidence. A quick google search will show you the number of people who've gotten off death row because of new evidence that exonerates them, and will also reveal those who have sadly been executed who were actually innocent.
