If I were to book a ticket to travel to somewhere in the USA from Europe right now, and I bring one large traveling bag and one small backpack with me, with the big one containing a baton (thus a weapon), and I only bring the backpack with me on the plane, will they scan/check the big one as well? And/or will they do that when I arrive to the airport in the USA?
After all, in terms of safety on the plane, I will be 100% unable to get to the big bag, since it's in the special, separated "baggage compartment" of the airplane. I will only access it once I'm back on the ground, at the airport.
The purpose of this would of course be to bring with me some sort of personal protection, although it would probably be useless against somebody sticking a gun at me. I have become so used to always carrying the baton on me at home, whenever I leave the house, that I would feel naked walking the streets entirely unarmed, especially in the USA.
I'm worried that they would scan the big bag anyway and detect the baton and proceed to harass or even imprison me for it. Technically, it's illegal to carry it here, so it probably is over there too, but it's not like I would be bringing attention to it. If they don't know about it, and it never is accessible to me while actually traveling, do they really care?
