http://www.cbc.ca/beta/news/world/dylann-roof-death-penalty-challenge-1.3703685 Dylann Roof's lawyers want federal death penalty declared unconstitutional Ruling would permit Roof to plead guilty and serve life for deadly shootings at historically black church Attorneys for the man charged with killing nine people at a Charleston church are challenging federal prosecutors' intention to seek the death penalty against him. Lawyers for Dylann Roof argue in a motion filed Monday that the death penalty and federal death penalty law are unconstitutional. Their motion asks that a judge declare the death penalty law unconstitutional. It says such a ruling would permit Roof to enter a guilty plea and be sentenced to life in prison without the possibility of release. Roof is also facing a death penalty trial next year in state court in connection with the June 2015 shootings at Emanuel AME Church. No date has been set for the federal trial. Authorities said Roof posed with the Confederate battle flag before the killings and talked of trying to start a race war.
