Speak no ill of the dying, ok, I can buy that because, as compassionate people we don't want to see people suffer. But speak no ill of the dead? Really what that means for most people is speak no ill of the dead for some unspecified period of time after they die.
Otherwise, we speak ill of the dead all the time for good reason. Who made the famous quote that those who do not study history are doomed to repeat it? We certainly, rightly, speak ill of Hitler, Stalin, Mao Tsung -- as well as countless others who affect politics and history -- for that very reason.
Some folks here are offended that Mr. Jennings death reminded people of his life -- which evoked memories of his liberal editorializing and subverting of the "news."
Apparently, that is considered "bad taste" -- even if he is a public figure and FR is a political forum.
