The U.S. Marine Corps has threatened to punish two members of the military legal team representing a terrorism suspect being held at Guantanamo Bay if they continue to speak publicly about reported prisoner abuse, a civilian lawyer from the defense team said Saturday. The action directed at Lt. Col. Colby Vokey and Sgt. Heather Cerveny follows their report last week that Guantanamo guards bragged about beating detainees. The order has heightened fears among the military defense lawyers for Guantanamo prisoners that their careers will suffer for exposing flaws and injustices in the system. Defense lawyers for Guantanamo prisoners say the personal stakes are high and point to the Navy's failure to promote Lt. Cmdr. Charles Swift after he successfully challenged the legitimacy of the Pentagon's war-crimes commissions. Two weeks after the Supreme Court ruled the commissions unconstitutional and lacking in due process, Swift was passed over for advancement and will be forced by the Navy's up-or-out policy to retire by summer. At least three other military defense lawyers for the 10 charged terrorism suspects have also been passed over for promotion in what some consider a subtle reprimand of their vigorous defense of their clients.
