Oklahoma doctor invents bullet-proof blanket for classrooms

A US doctor has invented this unusual defence against crazed gunmen who open fire in classrooms - a bullet-proof blanket. Steve Walker, from Oklahoma, said he developed the US$1,000 orange shield to give children greater protection from shootings and tornadoes. He said he was left frustrated by the murder of 20 children and six adults at Sandy Hook Elementary School in Connecticut in 2012 and by a deadly tornado that hit schools in Oklahoma in May 2013. On the product's Facebook page, some people have criticised the blanket's colour, saying it could draw a shooter's attention. Photo: SCMP Pictures
