Wisconsin teen invents device that could save lives during shootings
SOMERSET, Wis. -- A high school student in Wisconsin has created a device that could save lives in an active shooter situation. WCCO-TV reports Somerset High School senior Justin Rivard invented a tool he calls the JustinKase after noticing a flaw in his school's security plan. "The main problem was all these, all these kids in a building who have nothing but a door to keep them safe,” Rivard told WCCO.
