Doesn't clearing browser history work?

I use a public library PC often and there is nothing you can do about history there. It may log it but you can't see it, or use it. The government can, it is all about terrorism surveilance. They don't know who I am and only need the audit trail - in case.

Which is what double click want. The audit trail, so Google can target ads. Free is worth every penny. Free lunch refers.

When a million people can read your (not inconsiderable) thoughts - you worry about ads you can ignore?
