The death of Karl W. Marshall was the first time that someone in Kansas City police custody died after Taser use.
In other cases like this around the country, the death has been attributed to drug use or other causes - not the Taser. And the Taser maker, which says its product saves lives, fights critics.
But some police departments have amended their Taser-use policies after incidents. And Marshall's death promises to bring police Taser use here under scrutiny.
