Liberty Defense (SCAN.V) wants to make the world less dangerous

We live in a dangerous world. There are some threats that we’re capable of meeting, and some that are beyond us. This is what former secretary of state Donald Rumsfeld called the unknown unknowns: threats so oblique and sudden that they catch us unawares and leave us scrambling. So far, we can only add our culture’s random spates of violence in Rumsfeld’s category. We simply do not know why violence erupts in our culture, especially among our children, and all we can do is prepare for the inevitability.
