I can give my past experiences with Sanford PD when I worked in my "former life" as a security supervisor in Seminole County Schools. Most of the PDs in the area have officers that are on regular patrol but that receive special training in other areas. Many of those I worked with, for instance, were considered on the gang task force, but they were still on regular patrol as well. We all attended special meetings and briefings with the Seminole County Sheriff's, for instance, to keep updated on gang activity in that area and these officers would often be called to a scene if gang activity was suspected. Not all the officers attended these meetings as there just wasn't enough time for everyone to be involved in everything. They often are briefed separately and put more focus on their specialty, but back then at least they were just as capable as the next cop to attend to or secure a scene or deal with suspects, take a report, etc.
