The Davidson County Sheriff's Office has a new mobile booking unit aimed at getting police officers back on the street faster after an arrest. Such unit has everything required to fingerprint, take mugs shots, and holds up to 9 detainees. The unit is designed to allow officers to quickly complete an arrest without physically leaving the street for an extended period by eliminating the need for the officers to physically escort the detainee downtown and appear before a magistrate judge. Some have questioned whether the appearance before a magistrate can be avoided without raising constitutional issues.
