In many US states, 18 is old enough to buy a semiautomatic
The young age of the man accused in the Florida high school shooting that killed 17 people has revived the debate over age requirements for gun purchases.
Police say 19-year-old Nicolas Cruz legally bought the semiautomatic weapon he used to open fire Wednesday at the Marjory Stoneman Douglas High School in Parkland, Florida.
Cruz bought the gun just months after his 18th birthday. At that age, he was not old enough to buy any of the handguns at the store.
There are no such age restrictions for semiautomatic weapons, rifles or shotguns.
(However, all gun stores in Lincoln have chosen to require a purchase permit to buy such guns…and you need to be 21 to get such a permit.0
