True Story:
Went from DIA to New Jersey and then on to Amsterdam and connected to Zurich... and then, 3 Weeks Later... came back through Zurich to Amsterdam and hit New Jersey and then... suddenly... the fecal material came into contact with the air movement device!!! I used to... repeat: used to... employ one of my Carry On Bags as a Range Bag and I had inadvertantly left a Speed Loader, with 6 Remington .357 Magnum Golden Sabers, in it!!! Not only was the TSA a bit "put out" but, I soon discovered, the New Jersy Gestapo feel particularly strongly that
ONLY LAW ENFORCEMENT should be allowed to possess Hollow Point Ammo. Got Patted Down (no strip search... phew!!), Got Cuffed (I'm a big boy... it took two pairs of cuffs), Got Arrested (had to endure about two hours of various uniformed goons shouting, "Wheyas da' gun, azzhole?" [New Jersey, remember?] in my face... not fun), Got Booked, Spent 4-Hours in a Holding Cell, Released, Spent the Night (missed my flight... big surprise, huh?), Spent MONEY for a GOOD Attorney, Flew back to New Jersey, Rented a Car, Drove to Trenton, Explained my Foolishness to the Judge, Plead Guilty to the Reduced Charge of "Littering" (Yep... no lie... Littering), Gave 'em 4 Benjamins and got the hell out of Dodge before they changed their narrow minds!!!
Expensive little brain cramp, that was...
In short, I don't think that you or your mother in law will hear a peep about it from any Governmental-types ever again.
