Thanks.
A little nitpicking: in US it is actually a right.
It might seem weird for the rest of us but then again in their defense they never had a Srebrenica, an Auswich, a Rwanda in the last century so I guess it can be seen as an insurance:
They're paying a few lives every year to protect against genocides.
(And to be perfectly clear: I don't want that system here where I live, I just try to understand their situation.)
