"On October 14, 2007, a middle-aged man was growing irate at the arrivals terminal of the Vancouver International Airport. Robert Dziekanski had been stuck in the airport for 10 hours with a visa problem, unable to find his older mother. He couldn’t speak English—couldn’t speak any language other than Polish. So, frustrated or delirious, he had begun throwing furniture to the ground.
Four members of the Royal Canadian Mounted Police arrived to investigate the commotion. One of them gave Dziekanski an instruction in English. It’s unclear whether he complied, and it hardly mattered: Less than 25 seconds after getting to the scene, Corporal Benjamin Robinson, the senior officer present, ordered his team to use a stun gun on Dziekanski.
The police tased Dziekanski five times. He screamed, collapsed, and writhed on the floor. Instead of letting him sit up to catch his new breath, the officers forced his face against the ground as they tried to handcuff him. He resisted, then stopped fighting. When paramedics arrived minutes later, they could not revive him. Dziekanski’s heart had stopped."
