BULLET-PROOF STAND FOR SPEAKERS (May, 1933)
This doesn’t seem like it would offer that much protection…
BULLET-PROOF STAND FOR SPEAKERS
A bullet-proof speaker’s desk has been devised by engineers of a broadcasting system, to protect public men from the attacks of assassins when making addresses to large gatherings. Metal armor shields the body of the speaker from below his waist to a point several inches above his shoulders, when he stands upon a platform. Four microphone outlets are spaced across a panel behind the desk, while spring clips and a lamp are provided.





If it could block your head from your audience (and it might, if you were on an elevated platform), wouldn’t it prevent the audience from seeing you?
Why would anyone go to a speech if they couldn’t see the speaker?
