Public opinion turned against the Central Intelligence Agency as a result of evidence from what?

Public opinion turned against the Central Intelligence Agency due to evidence from the Church Committee investigations in the mid-1970s, which revealed abuses of power, including illegal surveillance, assassination plots, and unethical experimentation on citizens. These revelations highlighted the CIA's clandestine operations and lack of oversight, leading to widespread distrust and calls for reform. The exposure of these activities contributed to a broader skepticism about government institutions during that era.
