The OP references in specific to the show NOT to general life nor as in general overall toward attitudes of open carry.
The show provided a specific, not broad, scenario driven encounter which was multi-faceted, not flat, relating to the view of a citizen open carrying not just from one angle but actually three:
1. That of a concerned citizen; Who notified authorities which was not improper toward a sighting of literally a 'Man with a gun'. The show literally shows the citizen calling and exactly what he states to 911.
2. That of an otherwise lawfully acting citizen, who is a Man with an open carried as holstered gun; Who upon contact with police in three individual takes (NOT shown in the 5 sec. video clip) chooses to
A) Be defensive, combative and stupid as he grabs his gun just before being shot down by LEOs
[Show advises DO NOT DO THIS...To do so is gonna get you killed]
B) Be argumentative and by that actively resistant, to ultimately be arrested, toward what is immediately per context a Terry Stop
[Show advises DO NOT DO THIS...To do so is unwise]
C) Be understanding of the fact that you are in fact an MWAG, as stated upon initial contact by the LEO, and to from there be assistive as in answering any questions toward the validity of allowance as per state laws AND local bylaws toward otherwise exercising ones civil right as a US citizen; Which by manner of practical application fact are and always have been in the USA....Infringed.
[Show advises DO THIS...To do so will possibly be momentarilly annoying but in the end it will allow you to POSITIVELY represent not just yourself but ALL of the rest of us lawful carry civilians be we open or concealed as to both the LEOs (not all support us!) AND to the on watching citizenry who very likely are not aware of the details toward state laws and local bylaws as related to gun carry]
3. That of two LEOs (primary does all the talking while secondary is silent as in active support of primary) responding to a concerned citizen toward a call of 'Man with a gun' having no additional information offered other than MWAG @ location.
No additional information about state or local bylaws is provided as a preface and the LEOs do not contact the citizen in aggressive manner from the outset. They can CLEARLY see that the citizen is in fact a man with a gun which is why they selected him as opposed to any other Joe or Jane on Main Street in that moment, thus no additional 'search' beyond the visually obvious is necessary nor applicable/relevant.
The rest is as detailed above in the way of follow on result.
The rest of your concern and discussion goes off to areas that are NOT specific to the show and the scenario presented on the show, and thus are irrelevant.
If the OP had made a post discussing Open Carry generically I'd likely have never made a peep...Notice I very rarely ever post in this area and have never posted a thread; That is not coincidental.
I came in to add $0.02 toward what was a discussion of the show, and by that a specific scenario as presented within the show.
Anything else is, off topic.
To those who have not actually watched this shows episode, do yourself a favor and do so BEFORE leaping to a conclusion and taking a position on how something went and might should be toward what you have not otherwise actually seen.
This clip provided in the OP is just that, a clip, as in the form of a _commercial_ toward what was a well developed multi faceted situational 'Choose Your Own Adventure' style scenario.
You can't possibly take a position on this when you haven't actually seen anything but that clip. The clip shows NOTHING, but 5 seconds.
