It’s worth hiding counterfeit money in your luggage so a thief gets some serious jail time when they spend it.
Just let me know where I can find a few million.
Not really. If your counterfeit money is found in the event that TSA searches your luggage, you are on the hook.
And let's not forget that notorious arrest of George Floyd for passing counterfeit money, that ended up in national riots, astonishing amounts of lying, dissembling and blame-laying, a cop who folloowed procedure in prison for life, and a national stain that will last for decades.
