CIA sources on suspected Hezbollah spy: What's the big deal?

I love the excuse in the Daily News article. Sinister double agent? Or just crafty go-getter?

James Bamford, who has written several respected books on the intelligence community, said it’s not surprising CIA vets wouldn’t care that Prouty lied. It’s the difference between the CIA and FBI cultures, he said. “One agency teaches people to lie and break the rules. The other teaches them to tell the truth and obey the rules,” Bamford said.

While FBI agents are indoctrinated to be morally pure because they often testify in criminal trials, “the CIA is the opposite,” he said. “The CIA was founded on subverting laws, going over walls and under fences.”
