An extremely interesting particle. I highly recommend it.
That statement reminds me that in the C-Span program, Evans is very explicit about McCarthy never having made an unwarranted accusation or smeared any innocent person.
In fact, according to Evans, in the famous "Have you no shame, senator?" moment, McCarthy was being explicitly berated about identifying a red who had already been outed as CPUSA memeber in the NYT! (Shades of the Valerie Plame non-incident.)
And they are still there.
