You'd have to be off your fucking rocker to open carry, or conceal, around Obama. I'm not disputing your "right" to do so, but I will call into question your grasp of reality. This guy's gonna be on Secret Service lists for the remainder of his life.
The short list.
I've observed that, as a general rule, personal protection required follows a simple formula:
P = AC + C
where:
P = protection required
C = celebrity of protectee
A = asshattery of protectee
Obama is a big celeb, in town for a monumental level of asshattery, therefore protection required is through the roof.
Kostric (without his weapon) is not a celeb, but engaged in a low-level of asshattery as explicitly defined by the protectee and his devoted faithful. So, the personal protection he requires is very low. Certainly, he can provide that himself.
In this framework, Kostric (with weapon) is being criticized for two reasons:
A) By carrying a weapon, Kostric's P
actual is in excess of his P
required B) Because he's carrying it in the vicinity of a person with high P
required, Kostric's excess P
actual either:
b1) increases P
required of the protectee; or
b2) increases Kostric's asshattery, resulting in a higher P
required than his P
actual (self-referential, but that's the argument being made so go with it).
There's an additional assumption that the police/secret service/ABC agents can/will cover the P
required for everybody in the crowd. I think that's a bad assumption. If the feared event goes down, the protectors are focused on the protectee, and everyone else becomes suspected threats.
Therefore, you can't disregard a radiating function in the vicinity of a protectee with a high Prequired. It's an inverse relationship that's some function of distance that increases the P
required of everyone near the protectee and proportional to the P
actual of the protectee.
So the question is, considering all that, did Kostric
have a P
actual in excess of his P
required? As a one-off event you can't answer that question definitively, but you can see that the critiques being offered likely make Kostric's decision to carry more reasonable than the decisions of people who didn't carry.
I would question the sanity of anyone who goes near a protectee with a high P
required. I would doubly question the sanity of anyone who goes into that danger zone
without personal protection.
