Xe

Blackwater, the notorious mercenary company, has changed its name to "Xe" in a rebranding effort.

As science students should be aware, Xe is the chemical symbol for Xenon. As they will recall, Xenon is an inert gas: colourless, odourless, invisible.

However, Xenon dissolves in blood and can penetrate into the brain, causing anaesthestic effects.

Will Blackwater's change of name result in equal invisibility and political anaesthesia from the American population?
