to be a bump stock. The shots were too close together. Which supports my point in that the Guardian article was premature and thus not helpful.
Conversion kits to transform semi-auto to fully automatic are subject to the same Federal regulations as automatic weapons and thus illegal. It is most likely that the Las Vegas gunman did not obtain his guns legally. Which makes this a border control issue rather than a gun control issue.
As Tom pointed out, the Sandy Hook shooter killed his mother and stole her guns.
