The mistake wasn't in not blowing the whistle but it was taking a job with this kind of organization in the first place.

Yeah the solution is to not put yourself into a position where you need to make these choices. The fuel for the fire that are organizations like the CIA are people who don't have moral qualms or who have flexible ones.

The less people who work for these organizations the better.

I never worked directly for them. I was a contractor.

If all the people of conscience quit, they are left with a workforce without a conscience, which I guess is pretty much what they have now, at least in certain areas.
