Just watched this back, the two guys switching from “LE” to “GU” are well drilled.

Found this:

The leftist Separatist group in Basque, the ETA, considered the Guggenheim as a symbol of American Imperialism. Two members of the group were found posing as gardeners, attempting to plant explosives in the museum lawns to disrupt its inauguration. A member of the Basque police force, the Ertzaintza, was shot while trying to stop them.
