No. No pro would try a head shot much less try to hit the neck.
This was an untrained maladroit who tried for a head shot just like the Trump shooter did but this one had "luck" and hit something else vital.
Pros are trained to target just to the left of the sternum. Upper left chest - big target, can't suddenly move and contains guaranteed vitals like the heart and left lung.
I'm leaning towards believing it was a hired pro too.
They knew this event would be seen by 1000's live, and countless millions would have access to TV & Internet. Whoever financed this wanted a very gory, very vile statement made to scare everyone LIKE Charlie Kirk to go into hiding and never come into public again. Shooting the guy in the jugular from 200 yds with a scoped rifle would not be an overly difficult shot for most with any sort of training, and for a "pro" it would be a lay-up. This was pure terrorism with the intent on silencing one political side, because that side is winning. They wanted all that blood.
This was broad daylight, middle of the day, middle of a work week. All sorts of security cameras. People in those buildings. Yet it seems nobody saw anything, they have no pictures of anything. They don't even have a general description. This person had help and my guess is the shooter is well outside our country now.
