In case anons are interested, there IS level 10 bulletproof "glass." Not commercially available, due to the low number of people who expect to get shot at by a .50BMG. But…what I'm seeing on stage doesn't seem to fit the description.

Give it a read, and see if anything stands out:

That said, this is a first for POTUS. I think the deep state is far more afraid than we think, if security is going through this effort right now.
