Nice designs on the posters! But note that the information on the pro death penalty poster is misleading. It is unclear where the creator of the poster got the numbers, but in the United States, numerous studies confirm that the monetary cost of the death penalty is significantly more than the cost of life imprisonment. Because of the risk of executing innocent people and constitutional requirements, the cost differential begins at trial, when death penalty trials cost the state more than other trials. For example, see this compilation of some of the studies: <http://www.deathpenaltyinfo.org/costs-death-penalty>
