I'd go to the police and show it to them, and let an officer go to the bus company to discuss it with the driver and the manager. I'll bet there would be much more action. You can also write a letter to the local paper, not naming the driver but naming the bus company, and that will create negative publicity. Also start a petition and take it to the bus company demanding more action and a public statement about their policy. Call your TV news station and ask them to do an investigative report about this company and maybe a few others. Make the bus company defend themselves to the media. And of course the problem is that the driver will get transferred to another route, and the problem will start all over again. There have been reports in many cities of subway/trolley operators texting, with some major accidents. In Boston, the subway drivers can't even have a cell phone with them, even in their pockets. So make noise, and plenty of it. Don't be mollified just because someone got transferred to another route.
