Further consider that there's no note and I don't think we have evidence of him being suicidal. People do kill themselves without notes and people do hide their depression, but how many times do we say "well, all these things that are consistent with a lynching are possible in a suicide" before occam's razor forces us to accept that it being a lynching is a much more reasonable conclusion?

Was there any evidence, even retrospectively, of suicidality or a mental health crisis leading up to his death? Did something awful happen to him or a loved one? did he express being depressed even indirectly? Does this being a suicide make sense to the people close to him?

Black men sometimes get lynched with no real antecedent in their own lives (e.g. they may have no real connection to the killers), but no one deliberately kills themselves without antecedent. There is no neutrality here; if there's an overall absence of evidence, that leans unambiguously toward it being a lynching.

He didn't. If the cops says otherwise, that just means the cops were in on it.

if he hanged himself, then there's a high chance faced a lot of racism throughout his life and could be the reason of being suicidal.

It wasn't unprompted, they were responding to a question specifically about the internet rumors that there were broken bones.

"Bolivar County Deputy Coroner Murray Roark told the Mississippi Free Press that he “saw no broken limbs” on Reed, but did not elaborate due to the ongoing investigation.

“I don’t think I should probably discuss this any further than that, my opinion is that it was self-done, and I have reasons for that,” Roark said.

Should be huge alarm bells there. It's not rare, but uncommon for people to hang themselves in public. Two curious points are immediately being brought to mind with the history of the nation and state behind the scenes.
