Fox News reporter Geraldo Rivera issued an apology Sunday. Not for wasting our time with that whole Al Capone debacle. Or for that ugly chair-hurling melee that marred his late, not-so-great talk show. Or for all those bad hair days. No, Rivera expressed regret for breaking military rules last week when he revealed U.S. troop movements in Iraq. In an interview Sunday on Fox, he said he admitted he "should have been more careful."
