Shoot to Kill

A simple order, given to guards, when prisoners have rioted. Prisoners are given warning shots. And then, if order is not restored, disobedient prisoners are at risk of being shot dead where they stand.

Why do such a thing? To prevent stories like this containing lines such as:

[...] "The victims' heads were displayed on stakes on the prison roof." [...]

Harsh? Exactly. Riots in prisons are not to be tolerated.
