The government failing to protect a life is not the same as, or even similar to, the government erroneously taking a life.
Incompetence that leads to my wrongful conviction and death is probably just as likely as the incompetence that would lead to my death when I'm supposed to be protected. It's a hell of a lot less likely than the death of those whom I'm not-exactly being protected from, such as the countless victims of "collateral damage".
