The Massachusetts state is preparing for several World Cup matches at Gillette Stadium in June and July, with hundreds of thousands of international visitors expected to attend. The state officials have assured residents that safety is their top priority. The massive security effort, dubbed "Match Ready Massachusetts," involves 70 agencies, 351 local emergency managers, and $67 million in federal funding. An exhibition game between France and Brazil is scheduled for Thursday at the stadium. Governor Maura Healey toured the watch center at the Massachusetts State Police headquarters in Framingham, where officials will monitor public safety operations during the events.
