The Hennepin County Government Center is one of the few urban courthouses in the country that has not enhanced its security by adding metal detectors and entrance screening. Architects designed the structure to be an open and convenient center where visitors could move freely between two 24-story glass towers. For years, the Hennepin County board has debated whether to increase the building's security. County officials determined that adding metal detectors and x-ray machines at all of the entrances would cost millions of dollars. Mike Opat is the chair of Hennepin County Board of Commissioners. He says that, in light of today's fatal shooting, the building's security will be re-evaluated. He spoke with Minnesota Public Radio as he was boarding a plane heading back to the Twin Cities.
