Gintautas Dumcius reports in MassLive.com that on Nov. 3 Massachusetts banned bump stocks that turn semi-automatic weapons into automatic weapons. At the deadliest mass shooting in U.S. history last month in Las Vegas, the shooter used a bump stock while murdering 58 people and wounding another 489. California had previously banned bump stocks, which are legal in New York. Now, across the border, owning, selling, or buying bump stocks is illegal. The Gun Owners Action League, which is affiliated with the National Rifle Association, had lobbied for a veto of the ban.
