Hydrostatic equilibrium yes, but equal? No. We agree that centrifugal force is a factor. Now ask yourself, why would gravity suddenly strengthen at the equator to get the surface acceleration to stay equal to that of the poles?
It doesn’t. As a result the Earth seeks a new hydrostatic equilibrium, bulging out at the equator. This in turn strengthens the centrifugal force a bit while also slightly diminishing the force of gravity (because more of the planet’s mass is farther away). So the same effect is taken even further. Local differences add a layer of noise on top of this, but the end result is that the net surface acceleration is measured to average slightly less at equatorial regions than at the poles, with for example Singapore getting 9.7639 m/s2 of downward acceleration, while Helsinki gets 9.825 m/s2.
It wasn’t about George Floyd as an individual. It was about what that case represented. People weren’t rioting to get him back alive, they were angry at the system which caused his death among many others. Police killing black people is a thing that keeps happening over and over again in the US. It’s a systemic issue that is never fixed. Floyd just ended up being the face of a movement born out of a lot of frustration about police brutality in general, possibly because of the way that situation was filmed. If he hadn’t died, then some other case would’ve served as the catalyst for the same movement.
Oh and the exact manner of death was quite irrelevant. Either he suffocated due to having a boot on his neck, or then he OD’d and the officer killed him by omission, failing to provide medical attention. Most likely it was a bit of both.
