Hate to break it to you, but America IS a macho, gun-loving, power-tripping culture. What macho, gun-loving, power-tripping game were two man-children playing that got one of them so pissed at the other that he SWATted him?
That's what makes this so much worse - the guy who got killed never knew why the cops were there, which is presumably why he was confused and made the mistake that killed him. He died because he was innocent.
