I lived through the army - McCarthy hearings as a child: we watched them on tv every day. My parents, who were conservative Republicans, were appalled at what they saw. This video contains excerpts of the hearings as we saw them. The whole country was able to view what was happening--doctored evidence, bullying, intimidation, and a reckless attack on anyone who had the temerity to disagree with him. People were convicted--in Congressional hearings rather than on trial by jury--by association, by hearsay and by innuendo. While there certainly were some Communist spies and sympathizers, many people whose careers were distroyed were in fact innocent. For the first time, we could all see this as it was happening (This was the first time such hearings were broadcast). There was no "liberal slant" in those broadcasts: McCarthy convicted himself by his own actions. My parents, who were no liberals, became convinced by what they saw that McCarthy himself was a true danger to this country.
This documentary is well worth watching. The danger McCarthy posed was real: democracy's defenders sometimes, out of fear, risk distroying the very thing they seek to protect.
