Truthfully, I will have to watch it again...I half-watched but mostly listened to it twice...really was not watching and certainly not watching for shaking...and I am not sure what relevance shaking has on the actual content of his presentation...
However, you have piqued my interest, so I likely will watch it closely again tomorrow and try to note shaking.
It was trembling. Just go half way into the video turn down the sound and Levin is in a state of terror. Look at how the paper is moving like a geisha fanning herself. He got F’n busted as a criminal co conspirator and the law got layd out. The great one has been neutered, not that his balls ever dropped given his Fran Dresher voice. Jackass had it coming.
