I think they actually are allowed too...
Emergency Response Personnel
Police, fire department and emergency medical services personnel will be permitted to use hand-held wireless communications devices and view display screens in the normal performance of their duties.
The use of hand-held radios by amateur radio operators (who provide assistance, especially in emergency situations such as severe storms and blackouts) will be phased out within three years, to allow hands-free technologies to be developed.
