Do you believe the FBI and CIA will protect us from an autocratic president’s impulse toward tyranny? Read any biography of J. Edgar Hoover, long-time Czar of the FBI and hardly a good man. Browse any history of the CIA, the agency of American spooks which dates to the beginning of the Cold War when actual high ranking Nazis were recruited and given new identities in the US to help us fight the Communists (and keep the world safe for democracy).
Or read this (from Wikipedia on the JFK assassination), which contains no surprises:
The Church Committee is the common term referring to the 1975 United States Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities, a U.S. Senate committee chaired by Senator Frank Church, to investigate the illegal intelligence gathering by the Central Intelligence Agency(CIA) and Federal Bureau of Investigation (FBI) after the Watergate incident. It also investigated the CIA and FBI conduct relating to the JFK assassination.
Their report concluded that the investigation on the assassination by FBI and CIA were fundamentally deficient and the facts that have greatly affected the investigation had not been forwarded to the Warren Commission by the agencies. The report hinted that there was a possibility that senior officials in both agencies made conscious decisions not to disclose potentially important information.
Just a hint, you dig, a soupcon, a scintilla of an odor that the FBI, the same agency who had bugged the hotel rooms of Martin Luther King and attempted to get him to commit suicide with blackmail letters, the masterminds of COINTELPRO, had decided to withhold certain key facts about who was involved in the killing of an American president. Who’da thunk it?
You don’t need to be a conspiracy theorist to notice certain things simply by their bad smell. Trump meets with Vladimir Putin last July– nobody in the room but the two of them and their interpreters. We hear the president confiscated his interpreter’s notes at the end of the meeting. Nothing to see here. Why would anybody think differently? It’s not as if there are any allegations that the current American president, say, offered Mr. Putin a $50,000,000 penthouse apartment as an incentive to move things along with the Trump Moscow project in the months before the 2016 presidential election?
Note: I incorrectly corrected the price of the penthouse in the previous paragraph to five million dollars. I’d initially written fifty million, which seemed like an absurd price for an apartment. The Moscow penthouse Trump’s people apparently talked about offering Putin (and in fairness to fuckface, he may have lacked the “actual knowledge” that would have put him in violation of American law) was indeed a fifty million (FIFTY MILLION) dollar inducement. Yow.
When Cheney and Bush resisted the formation of the 9/11 Commission, and then agreed to testify only on the condition that they appear together, secretly, with no record of any kind made of their testimony and no oaths to testify truthfully taken by the president and vice president of the United States? Nothing to fucking SEE HERE!
The CIA, to give just one illustration, gained a certain notoriety during the Vietnam war for taking captured Vietcong up in helicopters to interrogate them and tossing them to their deaths. The CIA works the “dark side” and has done serious, er, mischief in every corner of the globe during the seven decades of its operation. The less said about them, in this instance, the better. No reason to even provide a link to something like this, or this (passionately written by a non-native English speaker, possibly a high school student, and containing this comical bit, at the bottom: This is the website of the American Civil Liberties Union and the ACLU Foundation © All Right Reserved) 
It’s not like the CIA ever refused to cooperate in a lawful investigation or did anything any patriotic American would not have done, in spite of this kind of facty thing from Democrat Diane Feinstein:
The 2008 review [of the CIA torture program and destruction of videotaped evidence of that torture– ed] was complicated by the existence of a Department of Justice investigation, opened by Attorney General Michael Mukasey, into the destruction of the videotapes and expanded by Attorney General Holder in August 2009. In particular, CIA employees and contractors who would otherwise have been interviewed by the Committee staff were under potential legal jeopardy, and therefore the CIA would not compel its workforce to appear before the Committee. This constraint lasted until the Committee’s research and documentary review were completed and the Committee Study had largely been finalized. source
Here is anti-Trump former CIA director John Brennan on the Senate Torture Report (keep this in mind, next time you see him speaking on TV about Trump being a clear and present danger to our nation):
CIA Director John Brennan – “It is our considered view that the detainees who were subjected to enhanced interrogation techniques provided information that was useful and was used in the ultimate operation to go against [Osama] bin Laden.”
The personification of evil, Dick Cheney, channeling his inner schoolyard bully at age nine, called the Senate Torture Report “a bunch of hooey”.
Ah, my friends, this is a rabbit hole with no bottom. You can fall into this, and keep falling, until history itself, even very recent history, the history of last summer, or last month, for example, begins swirling around you in an incoherent churning whoosh that will eventually have you chanting “Build that wall! Lock her up! Block that Kick! They all suck! Fuck them up! Eat my ass!” and pumping your fist as you fall.
All to say, do not put too much faith in the guardians of democracy to actually guard democracy, the worst form of government, except for all the others. (Churchill?)
 From Diane Feinstein’s foreword to her Senate Committee’s 2014 report on the CIA Torture Program:
As the Study describes, prior to the attacks of September 2001, the CIA itself determined from its own experience with coercive interrogations, that such techniques “do not produce intelligence,” “will probably result in false answers,” and had historically proven to be ineffective. Yet these conclusions were ignored. We cannot again allow history to be forgotten and grievous past mistakes to be repeated.
Our fully transparent government has a PDF of the report here (further proof that Mr. Trump’s chaotic administration remains severely understaffed, since he is, personally and professionally, a big fan of tough guy torture).
Speaking of lying piles of shit, let us not forget what president George W. Bush said of the 2006 Military Commissions Act that authorized the continued use of the torture that the Senate Torture Report would eventually, once again, find does not produce valuable intelligence of any kind:
“This program has been one of the most successful intelligence efforts in American history. It has helped prevent attacks on our country. And the bill I sign today will ensure that we can continue using this vital tool to protect the American people for years to come. The Military Commissions Act will also allow us to prosecute captured terrorists for war crimes through a full and fair trial.” source
Here are the Senate Torture Report’s conclusions, by the way, collected from the PDF on the intelligence.senate.gov website:
The Committee makes the following findings and conclusions:
#1: The CIA’s use of its enhanced interrogation techniques was not an effective means of acquiring intelligence or gaining cooperation from detainees.
#2: The CIA’s justification for the use of its enhanced interrogation techniques rested on inaccurate claims of their effectiveness.
#3: The interrogations of CIA detainees were brutal and far worse than the CIA represented to policymakers and others.
#4: The conditions of confinement for CIA detainees were harsher than the CIA had represented to policymakers and others.
#5: The CIA repeatedly provided inaccurate information to the Department of Justice, impeding a proper legal analysis of the CIA’s Detention and Interrogation Program.
#6: The CIA has actively avoided or impeded congressional oversight of the program.
#7: The CIA impeded effective White House oversight and decision-making.
#8: The CIA’s operation and management of the program complicated, and in some cases impeded, the national security missions of other Executive Branch agencies.
#9: The CIA impeded oversight by the CIA’s Office of Inspector General.
#10: The CIA coordinated the release of classified information to the media, including inaccurate information concerning the effectiveness of the CIA’s enhanced interrogation techniques.
#11: The CIA was unprepared as it began operating its Detention and Interrogation Program more than six months after being granted detention authorities.
#12: The CIA’s management and operation of its Detention and Interrogation Program was deeply flawed throughout the program’s duration, particularly so in 2002 and early 2003.
#13: Two contract psychologists devised the CIA’s enhanced interrogation techniques and played a central role in the operation, assessments, and management of the CIA’s Detention and Interrogation Program. By 2005, the CIA had overwhelmingly outsourced operations related to the program. [Neither psychologist had any experience as an interrogator, nor did either have specialized knowledge of al-Qa’ida, a background in counterterrorism, or any relevant cultural or linguistic expertise.]
(Note: The two fucks– Jessen and Mitchell, were nonetheless paid $81,000,000 by US taxpayers.)
#14: CIA detainees were subjected to coercive interrogation techniques that had not been approved by the Department of Justice or had not been authorized by CIA Headquarters.
#15: The CIA did not conduct a comprehensive or accurate accounting of the number of individuals it detained, and held individuals who did not meet the legal standard for detention. The CIA’s claims about the number of detainees held and subjected to its enhanced interrogation techniques were inaccurate.
#16: The CIA failed to adequately evaluate the effectiveness of its enhanced interrogation techniques.
#17: The CIA rarely reprimanded or held personnel accountable for serious and significant violations, inappropriate activities, and systemic and individual management failures.
#18: The CIA marginalized and ignored numerous internal critiques, criticisms, and objections concerning the operation and management of the CIA’s Detention and Interrogation Program.
#19: The CIA’s Detention and Interrogation Program was inherently unsustainable and had effectively ended by 2006 due to unauthorized press disclosures, reduced cooperation from other nations, and legal and oversight concerns.
#20: The CIA’s Detention and Interrogation Program damaged the United States’ standing in the world, and resulted in other significant monetary and non-monetary costs.
