Oh, Mr. Wilson...

Everybody's a-dither about whatever the CIA leak case prosecutor is going to do.
I have some questions.
They pertain to the ubiquitous Joe Wilson.
Didn't Mr. Wilson lie to the Senate committee investigating WMD?
Isn't there some sort of statute that forbids lying to Congress?
Shouldn't somebody be going after Mr. Wilson big time right about now?
Wouldn't the left get itself all a-dither about that?
And wouldn't the left let Mr. Wilson twist slowly, slowly in the wind if by some miraculous chance he should face charges of lying to Congress?
Answers, anyone?
