From what I've seen in the above video and the online videos and then comparing to what I heard in the LV videos, I have serious doubts that the LV shooter used a bump stock. The cadence in the LV video sounds too uniform to be bump firing. But, in the governments infinite wisdom, we don't need bump stocks or any machine guns ("thank" you Ronald Reagan and NRA). It doesn't matter that bad people do bad things with these weapons, the government (aka politicians - regardless of political affiliation) says we don't have the right to own one - of course, there are a few civilians that don't think we should have them - there are quite a few that don't think we need a semi-auto either. I don't really need a home computer either but I have one for fun, entertainment, and conducting personal business. But, mostly for fun and entertainment - just like firearms. I don't need computers, firearms, televisions or even cellphones but I want them. So, needing something is rarely a consideration. Oh well, what can one do except complain and file lawsuits? BTW, you, heh, need to shoot the video in a less noisy location for the commentary in the above video.
