Florida has been sued by the National Rifle Association after it passed a gun control law in the wake of a school shooting that took place last month leaving 17 people dead.

Florida’s Governor, Rick Scott, a Republican and staunch ally of the gun lobby, enacted the bill.

The law raises the legal age of buying rifles in Florida, but also allows the training and arming of school staff.

It does not ban semi-automatic rifles like the one used in the 14 February massacre in Parkland.

But it does introduce a three-day waiting period on all gun sales and a ban on bump stocks, a device that enables semi-automatic rifles to fire hundreds of rounds a minute.

The NRA filed its lawsuit yesterday (March 9) just an hour after the bill was signed by Governor Scott.

The complaint states that the law violates the second amendment of the US constitution, which governs the right to bear arms.

It also argues the bill breaches the 14th amendment’s equal protection clause by banning law-abiding citizens between 18-21 from buying guns.
