The ability to just flat out deny these things when they don't fit the narrative of the the government (any government) that people want to believe in.
If people think a given government is good, a large portion of them will not take evidence of said government doing something bad and revise their opinion of the government - they'll write off the evidence instead.
Even when said evidence comes from the very same government.
I attribute this to just a lack of education. I never learned in my public education the darker side of American history, and I think to a lot of people some of the crazy things acronym agencies have done sounds like conspiracy theory (bay of pigs, operation sea-spray, mlk suicide letter, MK ultra). And frankly, I get it, some of these things are fucked up enough that they should be fiction.
Except I think with a free encyclopedia being readily available (i.e. wikipedia) finally the average American is slowly having to reconcile their nationalism with their history. Hopefully change will come with that.
everyone jumps to the question of "does the end justify the means?"
a better question: why jump to the most brutal means before questioning whether the end is worthwhile regardless of the means?
is government mind control something we really want them to be able to do in the context of an intelligence agency? no, it is not; it is the apex of the opposite of human rights.
Is morality powerful enough to stop actions?
Government thugs can survive with a guilty conscience.
"A kills B" wrong
"A kills B".bind("B tries to kill A") righteous?
Or, like many things, they're made up of a mixture of good and bad people. Also, the CIA has either changed a great deal since the Black ops days of the 60s, 70s, and 80s, or they've gotten much better at cover ups.
In any case, they've indisputably saved Western lives in the past ~20 years. Even this week, Putin (!!) thanked the CIA for their help stopping a terror attack in Russia.
some people will believe MKULTRA is just a conspiracy people
and some people will view such actions as necessary but messy aspects of the brutally realist struggle between countries (critically forgetting that humanity comes before any individual nation or individual)
I saw some CIA recruits, they were not bright boys.
Three letter agencies were and are looking for a specific type of personality in recruits, types that are convinced that whatever they do is right, invariably of what they were told to do.
Three letter services are afraid of hiring people with brains, and even if they do hire ones, they favour people who can be said to be "intelligent, but witless"
Google Ryan Fogle.
The KGB never had a shortage of willing applicants. Money, power, being part of a secret society, and SERVING THEIR COUNTRY are things that a lot of men and women find incredibly appealing.
They must either be hiring really naive recruits, who are blinded by idealism or really ignorant of the history of the organization they're joining, or they're hiring complete and utter scumbags. Or, perhaps the revelations that have been made public about them are false and they're really the stereotypical "good guys" they try to paint themselves as.
