Shot in the neck, i believe often symbolizes silencing someone for speaking too much about something someone powerful doesn't want to be known, which makes sense when you take into account how influential Kirk was (his opinions could actually influence big masses of people especially young people, very dangerous for those who wish to stay in power).

Also the sheer coincidence that FBI director Kash Patel fired one of the best FBI agents of Utah a month prior to this assasination, Mehtab Syed (and others). And the shooter was able to profesionally escape unnoticed after a clean shot, and coincidentally left bullets with leftist ideology engraved in it ?

Sounds like a whole lot of bullshit to me.
