Rusty Rahm was perched on a stool, his legs tethered to the piece of furniture and his arms bound behind him. A man stuffed a wad of gauze into Rahm’s mouth and taped it shut, then shoved Vaseline up his nostrils. He sat like that for more than an hour as an EMT watched. “Obviously I was having trouble breathing at that point,” said Rahm, a 47-year-old entrepreneur who owns seven different companies and lives in Kansas City, Mo.
