Back in 2005, Beirut Blast Kills Foe of Syria (washingtonpost.com)

All the way in 2005, the UN indicted Syria for assassinating several Lebanese public figures, who opposed the Syrian occupation: Beirut Blast Kills Foe of Syria (washingtonpost.com)

The assassinations (and attempts) claimed the lives of Gebran Tueni, Samir Kassir, prime minister Rafik Hariri, George Hawi and Defense Minister Elias Murr and injured Marwan Hamadeh and journalist May Chidiac.  There were also a series of bombings that diplomats believe were intended to sabotage Lebanon's belief that it can be stable on its own.

The Washington Post article mentions that "Detlev Mehlis, a German prosecutor who is leading the probe, said he had uncovered new evidence substantiating charges of Syrian involvement in Hariri's death". 

Years later, in December 11, 2020 the Special Tribunal convicted a Hezbollah militant of Hariri's murder committed on Feb 14, 2005.  The way evolved human beings see this, all murdered dignitaries, the reporters, the authors, the activists deserved a tribunal, and if the Syrian occupation force seemed murderous to the UN before they left Lebanon by April 30, 2005, why were they left out of the 15 years long investigation that ended in 2020? It seems the death of the brave individuals who resisted the Syrian occupation was used as a tool to pressure Hezbollah, even if that meant absolving a murderous Syrian regime.
