Wednesday Execution for Nevada Murderer:  A Nevada man convicted of aggravated murder in 2007 and an earlier murder in Arizona, is scheduled for execution on July 11.  David Ferrara of the Las Vegas Review-Journal reports that two years ago Scott Dozier asked the state judge overseeing his case to allow him to waive his appeals because he wanted to have his sentence carried out.  Dozier's attorneys and the American Civil Liberties Union have petitioned for a stay arguing that state officials have not disclosed how the execution drugs to be used were obtained, and that the state's current three-drug protocol might cause pain.  For his part, Dozier told another reporter Monday that he doesn't really care if he suffers. Critics call his request a bid for state-assisted suicide.
