The shop Fentanyl Floyd went shopping was dealing Meth to raise funds for Jihad.
He went there to buy meth.
They conspired to sell Floyd a meth baggie with a lethal dose of fentanyl in it, and then rang the police to report a his odd behavior.
It's no coincidence that the cameras were rolling.
Most likely it took several attempts to get one on camera, so it would be interesting to see how many other folks died around the same time.
It was a setup, deliberate murder, filmed to inflame passions.
