I had a window seat, two rows behind the driver, who was encased in a bulletproof Plexiglas box.

Men with guns were everywhere and there were more of them behind the greenish tinted bulletproof Plexiglas of the blockhouse.

Just, I want a whole show with the Pope just bouncing around in that all-terrain Popemobile, with the three feet of bulletproof Plexiglas around him.
