Contrary to Michael Smerconish's claim, the federal judges who found Mumia Abu-Jamal's death sentence unconstitutional did not act on a "preposterous claim" ("No doubt on guilt, but fighting on was futile," Dec. 11). Instead, the courts were properly applying a Supreme Court decision when they recognized that the instructions given to Abu-Jamal's jury were so misleading that his 1982 death sentence was likely the product of a jury that relied on the wrong legal standard. Death sentences throughout the country were overturned by the Supreme Court's decision.
