It seems on the one hand that government “leaks” are libertarian, because they inform us about alleged state secrets.
But some information really ought not to be leaked. Let’s say the FBI investigates Smith. In the process it uncovers a sizeable amount of information about Smith’s personal life that no one knows but that could, if made public, embarrass Smith greatly.
For example, the FBI finds out that Smith one time had sex with a pig. I really think it benefits all of us if the government keeps rather than tells Smith’s secret.
Any one of us could be Smith.
