Prometheus 6

Former homeland security secretary Michael Chertoff, who joined the board of the Holocaust museum in January, likened von Brunn to the assailants at Columbine High School in 1999 and at Virginia Tech in 2007 -- "cases of individuals pursuing their own political agenda, no matter how disturbed they are" -- in contrast with domestic groups across the political spectrum who pose a terrorist threat.

If von Brunn acted alone, Chertoff said, "we certainly need to make sure we deal with it from a security standpoint, but it's not the same thing as talking about international terrorism on the other end of the scale. These are all security issues, but it's important to . . . treat them as separate kinds of problems."

They certainly are different kinds of problems.

Domestic terrorism is far more dangerous...no smuggling of people or equipment necessary, no way to stop you from buying all the weapons you need to execute your plan.
