Mo, what happened is really horrible, but I don't believe for a minute that the illusionist involved did not recognise the risks they were taking.
Until someone answers, I will keep asking the question of how this illusion SHOULD have worked. It wasn't magic and no-one believed that it was. Something went very, VERY wrong, and I will harrass every single illusionist I know until we find out what "should" have happened and what went wrong.
I don't place much credibility on the footage which is already online but I sure as heck want know why the paid security people weren't carrying loaded, live ammo guns in a "will carry" state. Are people who live in Nevada and carry weapons absolute FWs?
