Listen to what Trump actually said rather than relying on the misleading headline. Will POTUS end up banning all bump stocks? I don’t know. But his statement today doesn’t explicitly state his intention to ban all bump stocks. From the Medal of Valor ceremony today, he directed Sessions to “propose regulations to ban all devices that turn legal weapons into machine guns.” Does that necessarily imply a ban on all bump stocks? Possibly not, but I really don’t know.
Anyone can go to YouTube and listen to what POTUS actually said, and make up their own mind.
1) Those are already "illegal" under the National Firearms Act and the Hughes Amendment
2) Both of which are flagrantly unconstitutional and
3) Should be repealed.
