At the 12:22 mark Nima shows a video of Charlie's successors: 

Israel is the most likely candidate to be responsible for Kirk's assassination. Kirk was leading the younger American generation away from the typical American response that everything Israel does is justified.

Kirk was being funded by the Jews, but when they lost control of him, they cancelled their funding:  "Charlie Kirk leaked text confirms he was livid about bullying Jewish donors: I am leaving pro-Israel cause." Tucker Carlson reports that Kirk's turn away from being an apologist for Israel resulted from Kirk's realization that the United States was being used to fight wars on behalf of Israel.  With Kirk's assassination, Israel has now again taken control of Turning Point.  

The man in brown shown in this video.  The original video attributed Kirk's death to a low caliber palm pistol.  A subsequent interpretation concluded that the man in brown was detonating an Israeli microphone on Charlie's shirt, and that Charlie was killed with the technology that Israel used to wipe out the leadership of Hezbollah, an Arab militia in the way of Israel's expansion into south Lebanon.
