The fact that the CIA is admitting they don't have the shooter and also telling us to be calm and that everything is under control, makes me suggest that the Russian Sleeper who done the dirty deed was caught, and maintaining the ruse lets the Kremlin know that we know that Russia is attacking the USA trying to start exponentially growing avalanches of inward facing violence in America by Americans against Americans, in retaliation for the war in Ukraine. Anything that appears to be a pre-tensioned ready-to-avalanche fault line of inward facing energy and violence, would then become a place of maximum glowie focus, for honeypotting any Kremlin activated sleepers to try to be that perfect wedge in that perfect crack, that makes America burst into direct violence against itself. Literal Devout Christians from birth calling for a holocaust of Christians, and setting fire to churches to show the Jews what it's like to live under Israeli Zionist occupation.
