This should be part of modern history American students are required to study prior to graduation. He suffered unimaginable torture before being murdered by a CIA/FBI collaborating cartel. And, just as with the murder of Brian Terry who dared expose the Fast & Furious gun trafficking, involving Holder (with the president's knowledge), those in power have never been held accountable.
FACT: Although the CIA was created, without public support/approval, in 1947, "secret" operatives had long been utilized serving the interests of oligarchs, corporations, and political puppets controlling our government. Granting themselves power to control information---the absolute authority to deny, redact, and destroy-reports, testimonies, and other evidence ensures they can target, malign, intimidate, destroy, or assassinate victims, witnesses, whistleblowers--along with their family members if they are a threat to their power and control.
Despite their best efforts, however, conspiracy revealers/acknowledgers are finally in the majority--recognizing the political system is a farce used, just like covert initiated/funded/armed groups and orchestrated false flags/plandemics, as a means to distract and divide citizens from organizing to restore independence, personal freedoms, justice, and complete transparency in government.
