Perhaps you're aware that in recent days, the Dallas Police Department's moved to Twitter and Nixle in order to send out alerts -- such as Tuesday evening's press release concerning a suspect in the Skillman-Mockingbird area who, since October, has been responsible for at least four burglaries, one robbery and one sexual assault. But a Friend of Unfair Park forwards along a notice from Central Patrol Division that lists other departments now tweeting news and warnings: the City of Dallas Officer of Emergency Management and Dallas Fire Rescue. Says Lt. Andy Harvey, DPD spokesman, in the press release sent out yesterday, "Using social networking services such as Nixle help us keep our city informed and also serves as a crime fighting tool." Says another Friend of Unfair Park, "It ain't CueCat, but it helps fight crime!"
