n0m, nobody could be that stupid. You are lying on purpose.
Floyd was definitely not murdered. There is no doubt of that. The worst possible verdict is manslaughter by neglect, i.e. the cops should have checked on him more frequently, and once he stopped struggling they should have moved him to a different position. Maybe.
But the main cause for his death seems to be the large dose of fentanyl that he had just swallowed, and his generally bad health condition. He brought his own death on himself, just like Eric Garner did. Pressure to his back (not his neck) may have contributed slightly, and may have been the factor that pushed him over the edge he had placed himself at. That is all.
