If anybody else so much as walked out with a paperclip, they'd do 20 years. I'm mad as hell about this.
As well you should be. However, don't let it get the best of you.
If a foreign government is involved, then this may be an American counter-intel operation. Under that scenario, the hasher Berger is punished for his theft and destruction, the more valuable it makes the intelligence involved appear to be (so conversely, giving Berger an ultra-light sentence would tell a foreign government that Berger didn't get anything of value).
The intel world works backwards, remember, and all is not as it appears.
