Darth Vader police masks

Anti-riot police in the 12 Brazilian states hosting the 2014 World Cup will wear masks inspired by Star Wars villain Darth Vader at demonstrations by the Black Bloc protest group. Designed to protect against gas attacks, the masks can withstand high temperatures and have a visor that does not fog up. They have a voice amplifier and a tube through which the officers can sip water and use an air filter that can be linked to an external oxygen tube.
