One of the most horrific sounds coming from videos of the recent mass shooting in Las Vegas, was the automatic gunfire emanating from the Mandalay Bay Hotel. It is reported that the gunman used bump fire stocks to increase the firing speed of his semi-automatic weapons, in what was the deadliest mass shooting in US history.

Now YouTube has taken the step to ban all content showing how to adapt guns to fire more rapidly. The Telegraph reports that YouTube has deleted content that shows how to modify guns using a bump stock. A bump stock device costs around $100, turning semi-automatic weapons, which shoot one bullet per trigger pull, into automatic weapons that can fire a lot faster.

"We have long had a policy against harmful and dangerous content. In the wake of the recent tragedy in Las Vegas, we have taken a closer look at videos that demonstrate how to convert firearms to make them fire more quickly and we've expanded our existing policy to prohibit these videos," a Google spokesperson said.

Regarding harmful or dangerous content, YouTube states, “Videos that we consider to encourage dangerous or illegal activities include instructional bomb making, choking games, hard drug use, or other acts where serious injury may result.”

Gizmodo reports, however, that many instructional videos on how to convert semi-automatic rifles into fully automatic rifles still remain.
