The lockdown of Boston because of a terrorist on the run was excessive. It didn't work (he was found as soon as they ENDED the lockdown because someone went outside and saw him). And as further evidence, the police literally told doughnut shops to stay open so police could stop by for snacks.

Intercepting Predator Video: Schneier on Security
Bruce Schneier defends the lack of encryption on the video channel for predator drones. He says the key management would be horrible, and the risk of NOT giving the data to someone in the field who needs it is greater than the risk that bad guys can benefit from it. He proposes perhaps the military needs a new protocol that is less stringent for applications like this - perhaps you would be allowed to say keys over the telephone, for instance.
