Vice/Intelligence Unit

The purpose for the Vice/Intelligence Unit is to actively enforce and abate liquor law violations, human trafficking & commercial sexual exploitation of children (CSEC), pimping/pandering, prostitution, tobacco ordinances, illegal gambling, and other crimes deemed immoral within the city. The Unit is tasked with reducing if not eliminating these crimes within this jurisdiction. The Unit also reviews and approves security site plans for proposed new developments and reviews and approves various permits for new specified businesses, events proposed within the city, either on public property or on private property. This component is extremely important in thwarting potential issues, which would and could lead to a degradation of our community.
