Alright,the guy didn't threaten anybody,and I understand the "Im glad he had the balls to exercise his rights"and all that.....but we're talking about a presidential event here.
Like it or not,the Presidents life is more important then a protesters rights,or even a protesters life,and a gun,even when 100 legal,is seen as a possible threat.
I believe that what he did was an irresponsible thing to do,especially considering the atmosphere that is surrounding our current President,and the tensions that fill the air regarding his policies,his citizenship,and other controversial things.
Attempts have been made for less controversial things then what this Presidential administration is know for.
Having weapons in plane view during a Presidential event,Presidential motorcade,or anything otherwise considered Presidential is showing a lack of common since.
They're far better ways to exercise ones rights,and get your point across then to do this.This guy is no better then Code Pink in the way he takes things a bit far in an effort to be noticed.
