"They were aware that they were bringing in young people who had to adjust to the culture — and who would change the culture," said Joel F. Brenner, a former NSA inspector general, quoted in a NYT article titled "For Snowden, a Life of Ambition, Despite the Drifting."
The article also says that Snowden's disclosures highlight something the elders in the agency have worried about for a long time: "young Internet aficionados whose skills the agencies need for counterterrorism and cyberdefense sometimes bring an anti-authority spirit that does not fit the security bureaucracy."
What a fascinating culture clash! These old security folk are dependent on these new people who not only don't share their values: They are a completely different kind of person. Snowden is an example of a type of person that we need to understand. I'll call such people Snowmen.
Tell me about the Snowmen....
