Feb. 1 (UPI) -- Massachusetts' law banning the purchase and possession of bump stocks went into effect Thursday, making it the first state to enact such legislation since the devices, which increase a gun's rate of fire, were used in a deadly attack in Las Vegas.
Gov. Charlie Baker signed the legislation Nov. 3, a month after Stephen Paddock opened fire from the 32nd floor of the Mandalay Bay Resort and Casino, killing 59 people. He used bump stocks on multiple semi-automatic firearms in his hotel suite, effectively making them fully automatic.
