Title was mangled. The actual quote is:

> It's bad civic hygiene to build technologies that could someday be used to facilitate a police state

Not “avoid building technologies that could be used by a police state”, as the HN title currently says.

The HN title reads like any technology a police state could ever use should be avoided. Like cars, or pencils. Anything.

Schneier’s quote says “used to facilitate a police state” is a lot more specific: could be used to bring a police state into existence where it wouldn’t have been possible before, like having a database of everyone’s sexuality, etc.
