There won’t have been anywhere near the same level of security for Charlie Kirk though, so very easy for someone to get themselves into a position unnoticed. Apparently Utah permits carrying guns on campuses so even someone walking around with a gun (not sure if it’s an Open Carry state) wouldn’t necessarily raise eyebrows.
One thing I’d agree with, and it’s a comment not a conspiracy theory, is that the shooter was obviously well trained. Reports state the shot was fired from some distance (I though I saw 200ft mentioned) and to hit a single target with a straight “kill” shot (as opposed to just spraying bullets at random) does not happen through sheer luck.
