IS THERE A PILL FOR THIS MALADY?

An American, Abraham Lincoln, was assassinated by a fellow American, and some Americans cheered.
An American, John F. Kennedy, was assassinated by a fellow American, and some Americans cheered.
An American, Martin Luther King, was assassinated by a fellow American, and some Americans cheered.
An American, Anwar al-Awlaki was assassinated by fellow Americans, and many Americans cheered.
The important difference among these four assassinations by fellow Americans was that only the last one was carried out by government employees acting in accordance with immoral, un-American, but official government policy.

I don't feel a bit safer because al-Awlaki is dead. But I do feel a bit sick.
