during the las vegas shooting, stephen pattock supposedly expend over 3,000 rounds of ammunition over the course of 10 minutes from 27 ar-15s with bump stocks. despite the fact that that would have required him to drop a gun after each 30 round magazine was empty and videos from the survivors show that it was a non-stop stream of bullets with a firing rate much higher of that a bump stock is capable of producing, coming from multiple locations which appear to be m240 LMGs. After the FBI took over the investigation, his house somehow burnt down along with all the evidence and photos of his hotel room where he shot from shows only about 50 spent shells. Years later we don't know his motivation and there was strangely no follow-up on the largest mass shooting in us history.
