Predates video so it most probably is a kinescope recording.

There is much I could say about this woman but shall restrain myself and leave it to each of you to decide for yourself. One thing I do admire about her is that, according to the recording, she went to jail 8 times because she continued to advocate publically her beliefs in contravention of the law. Years ago Bishp Fulton J, Sheen observed, "We have the truth, they have the zeal". Would that we Christians and Conservatives were as devoted to our cause as are the anti-life/Collectivist forces to theirs.
