On Wednesday, 150 federal and state agents raided The Scooter Store headquarters in New Braunfels, Texas. Last year, former employees told CBS News the company's main goal is not to help patients -- it's to pressure doctors into writing prescriptions to boost profits. Once a doctor has written a prescription, Medicare rarely verifies whether the chairs are actually necessary. Former employee Brian Setzer described the process this way: "Bulldoze and get them to get the paperwork done."
