Would you endorse secretly spiking a stranger’s drink with uranium?

To make this scenario more comparable, you would need to randomize the amount of uranium because you would need to be unsure of the effect of the dose. You would also need to do this to schoolchildren.

You would also need to be the US Army or acting under the authority of the US Army.

You would also need to be immune to prosecution and to any legal remedy sought by the survivors.
