The female officer also attended to Husain and left Franco unattended. Was Husain resisting when the female officer went to assist? If the male officer asked for her assistance with a compliant Husain, why did the male officer who was in overreaction mode not think, "hey, let's put cuffs on Franco because I'm overreacting". Instead, we have confirmation from Franco that he was never handcuffed.
Husain doesn't look like he is resisting when the female officer comes over, no.
As I already said, I don't know procedure and I don't know that somebody who is compliant
right now means they won't or shouldn't be cuffed. I don't know if the female cop should have cuffed Franco. I don't know what the male cop thought about Franco. Perhaps he thought Franco was compliant and it was the female cop's judgment call to make. Perhaps he didn't know Franco wasn't cuffed. Perhaps he didn't call over the female cop at all.
I don't know. And with the amount of unknowns, I also don't know whether any actions happened solely because Husain was dark-skinned. I don't know what the police officers were thinking. I don't know why the female cop reacted to her suspect differently than the male cop did to his suspect. I don't know what was said between the cops. I don't know what the cops were told before they arrived on the scene.
I don't know these things and I am not willing to condemn people just because some people are convinced they do know.
