Law enforcement is exempt from not being allowed to drive and use a computer at the same time. However I have personally seen them drift and almost hit me while doing it, or while talking on the phone. I have even seen one officer on a cell and typing on the computer at the same time. It is not safe, but there is nothing we can really do about it and I just ignore it and say out of their way. I almost t-boned a cop car one day for failure to stop at a controlled intersection with no lights or siren. I know they were going to a non-emergency call and probably looking at the screen for the additional info that is not sent over the radio. I just gave the officer a dirt look as they passed me because I was at a complete stop.
