Let's talk people! It's not personal. Let's talk this shit out
I honestly could not care less about Floyd, his family, rioters, most of the protesters, celebrities and government officials virtue signaling. But I do see the need for a change in restraining tactics. The man was down, his hands on his back, with two other officers on his back and another standing by. It looked to me as if the kneeler was enjoying a hero complex(a kind of giddiness derived from submission of another). So that in my eyes, is abuse.
An obvious observation I see nobody mentioning is, why was Floyd wrestled to the ground. Answer: He was fighting the law. When you start wrestling/fighting with another man, it is to subdue him. What would Floyd have done after subduing the officer? Would he have run away(leave friends and truck behind), punched officer in the ground, take officers gun? These are questions that race through an officers mind in the instant the struggle begins. As a Law Enforcement officer, you have firsthand knowledge of situations going south pdq. Because of no personal relationship with people they encounter, it is impossible to meter how the person will react in said encounter.
To wrap up, I think Floyd messed up. He was high, maybe still had drugs, and made the wrong choice. There already was consequences associated with his actions, but he chose to act further. So answer is no, I do not back Floyd.
