The ballot drop boxes in Washington and Oregon both have fire suppression systems that are designed to activate when the temperature inside reaches a certain point, coating ballots inside with a fire-suppressing powder.
For unknown reasons, the system failed to prevent the destruction of hundreds of ballots in Vancouver, just across the Columbia River from Portland.
With a sufficiently not-fucking-around response to the terrorists who did it, betcha won’t need guards.
But America is gonna wrist slap nazis and say please.
