Transcript for Sen. Feinstein introducing bill to ban bump stocks after Vegas shooting
We are introducing me bill today with 26 co sponsors. And it has to do with these stuff. And with this particular. Food life that's easy to put on these weapons. We have now witnessed the deadliest mass shooting in United States history. Nearly sixty killed and more than 500 injured those numbers are simply stunning. In just nine minutes. And individual was able to turn it concert venue into a battlefield. One person nine minute. Utter devastation. We now know that shooter had at least 23 weapons. We all know that a dozen of those semiautomatic rifles were outfitted. With what are called. Stock devices. Bumps stocks which costs less than 200 dollars. Increase a semiautomatic. Rifles rate of fire. From between 45. And sixty rounds per minute to between 40800. Rounds per minute. That's the same rate of fire as automatic weapons and the only reason to modify them. Is to kill as many people as possible in as short a time as possible. There's a long history of laws to ensure civilians don't have automatic weapons. Strict laws were put in place after the saint Valentine's. Day massacre. In 1929. When Thompson submachine guns were used to kill seven gangsters in Chicago. And in 1986. A law was signed that banned all new machine guns for civilians. And put in place extremely strict regulations. On existing automatic weapons. However. There was a loophole. These bonds stocks devices. Which were likely used in Las Vegas. So anyone how to modify. Illegal semiautomatic. Weapon so we can function much like a fully on them. Weapons. It would ban the sale transfer importation. Our bill is simple and straightforward. Banned manufacturing. Or possession of accessories. That accelerate a semi automatic rifles rate of fire to that of an automatic. Weapon and it was part of the last assault weapons bill we did. Senator Murphy and on cosponsored that. And I should say I was hoping that more of our members would be here we have 26 Democrats. In less than an hour. Delighted senator Blumenthal and senator Sanders are here. So those who violate the ban would be subject to the same penalties. As those who illegally possess machine guns. Closing this loophole. Actually should not be a partisan or political issue. There's been broad agreement for decades the automatic weapons should not be legal and what we saw. Was an automatic weapons being used. And my understanding is that he had twelve. Of these devices or similar devices in that hotel room. Summitt said we shouldn't do this now we should wait now is not the time. Ladies and gentlemen win is the time going to be there. There is no better way to honor the 59 people who were slaughtered. Then to tack action take action to prevent this from happening yet again. If not. When will we ever do it after com mine I thought we would act after Virginia Tech I thought we would act. After Tucson when whenever colleagues who shot in the head and nearly killed I thought we would act. After a roar horrible thing in the movie theater I thought we would act. And particularly. After sandy hook went when he first graders were slaughtered. I thought for sure we react. After or Alando I thought we would act and now after Las Vegas. I hope senators will finally summon the political courage to stand up and say enough is enough. We can't sit by this deadliest mass shooting. It is really time for action we cannot do nothing.
