Good Sense

As usual, Bruce Schneier talks good sense.

This essay from 2007 that he links to in that post is particularly apt.

If you want to do something that makes security sense, figure out what’s common among a bunch of rare events, and concentrate your countermeasures there. Focus on the general risk of terrorism, and not the specific threat of airplane bombings using liquid explosives. Focus on the general risk of troubled young adults, and not the specific threat of a lone gunman wandering around a college campus. Ignore the movie-plot threats, and concentrate on the real risks.

Attacks like the one in Newtown are ultimately not psychology problems, or gun problems, or school problems. They’re security problems, and may or may not have elements of those other things. The problem isn’t as narrow as how to ban guns, or how to help crazy people; it’s how we can increase our security. Don’t just make up your mind on a solution, regardless of the details of the problem; focus on the problem and come up with a real solution. Or find you may not need a new solution at all.
