How many people would a 7 lb Cyanide block kill?? More than 100??
If you threw it in a local water supply tank..would it contaminate it enough to kill a local populous??
It is a chemical weapon....the Soviets had stockpiles of the stuff and so did we during the Cold War.
My more immediate question is why a salt block? for transport? are they now targeting perverted American cattle and sheep? What?
There must be something going on there.
