Jessica Flores writes: “[Contra Costa County (Calif.) Library’s Antioch branch] was scheduled to reopen February 20 after it was closed over the weekend due to several ‘dangerous incidents’ in the last few months, officials said, including theft, drug use and public sexual activity.” The library announced the closure in a February 16 Facebook post. Antioch’s mayor expressed concern at the closure in a February 16 letter to the county administrator. In preparation for reopening, the library negotiated an emergency contract to “provide private armed security and a patrol car to monitor the parking lot and library property,” in addition to the private security officer already inside the branch during library open hours.
