Crazy. If you get a permit do they not explicitly tell you carrying your gun across state lines may result in a felony? I'd think people would be wary of that. And also taking guns on a plane... to other countries.
Ya know, maybe it was one of those big backpacks and the gun was in an interior compartment and he just forgot about it. I know people that have camp knives and stuff in their bags and have accidentally carried them onto planes.
They do. Multiple times. My CCW instructor was very adamant about letting us know about it, and know how the laws vary from state to state even if they have reciprocity among them. And if they don't (i.e. California and NY, which IIRC don't have reciprocity with any other state), then you would need to get another license from that state if you want to conceal carry there. And even if you carry a gun up to their standards, i.e. have a gun in a locked case in your glove compartment etc exactly as required in California, but you have a higher capacity magazine than that state allows, that is still a felony and you can do either 10 or 25, IIRC.
