Imagine a hoax, in which a “travel agency” arranges for Europeans to come to the US, provides them with a map of a “bad part of town”, and a weapon, and lets them go “hunting” predatory criminals.
They provide them with an armed backup in the shadows, in case they are either surprised or outnumbered. When they are attacked and lethally defend themselves, then their backup takes some pictures of the scene as proof, disposes of the weapon, and cleanses the scene of any DNA with bleach, as needed.
All very illegal, and very expensive. Exclusive.
In any event, as a hoax leaked to some European websites, imagine the hilarity when the nanny governments learn of it and are horrified, and try to stop it.
I like the way you think.
