When i used to work for the police (not as an officer), we were provided with bluetooth kits (civies and police personnel) to use in our cars. Well so long as you asked for one. Also due to the department i was in, i also had a police radio and you can use those at the same time as driving. No hands free, worked as a phone or a push to talk. I suppose they could do fellows workers for driving without due care and attention. Also if you look it into more closely, its not so much the phone thats been banded its devices that operate on the public radio spectrum for mobiles and radios, hence making it only legal for police to still use their radios whilest driving as they use a different digital radio spectrum.
