Not exactly a prediction, but the fact that "Sen. Dianne Feinstein (D-Calif.) included a ban on the devices in her failed 2013 bill to ban assault weapons" would suggest that at least she saw the potential for these things to be used to subvert the laws against fully automatic weapons.
Yes, he did have at least one rifle fitted with a bump-stock.

Look, while I understand that these bump stock/slide fire attachments are not technically illegal, I wish the gun advocates here would stop burying their collective heads in the sands of denial by pretending that these are anything other then a way to make a semi-automatic weapon attain a rate of fire approaching that of a fully automatic weapon.
The fact that they don't alter the firing mechanism is totally irrelevant. The only thing that matters is that they allow the shooter to have a high rate of fire approaching that of a machine gun, allowing someone like Stephen Paddock to shoot more people than he otherwise would.
Here's the thing - "bumpfire" existed long before there were any commercial product to facilitate that function.
I can do it. I learned about as a kid on the M1 carbine over 50 years ago. I can do it with a handgun as well. There are many videos on YT explaining the procedure.
As a practical manner the stocks are already going to be banned, but the actual function that is being addressed can easily be duplicated by someone who wishes to do so without any such device.
