Law passed in 1968 prohibits licensed gunsmiths from selling guns to young people. Supreme Court ruled in June that the law must be part of the U.S.
Constitution. Young people commit firearm-related homicides at a rate three times higher than adults over the age of 21, according to the CDC. The decision is expected to be appealed and could end up in the Supreme Court, which has the power to ban gun sales to under-21s in the United States.
