If you have a permit and it is not concealed you are "brandishing" your weapon. If you pull it out, use it otherwise you can be the one getting in trouble.
I still think someone needs to look into the allegation that US agents told him "no problem just declare it on the otherside" Has anyone ever had that happen at Lukeville? Has anyone ever forgot they were carrying when they hit the border? If so, what did you do?
I am very happy for him and his family (seriously) but I don't get why he would think he could just show up at the border with any gun. I have a hard time believing the US agents said "no problem that you have a gun" i havn't tried it yet but when they ask me if I have any weapons or money over...
