Arguing the officer behaved badly is a different argument than everyone is racist. Everyone not need be racist for an officer to behave badly.
We need not push the narrative that this friendly and well behaved group of youngsters looking to have a nice refreshing swim encountered an inexplicably racist HOA policy which smacks of the historical segregation of pools, were assaulted by a racist security guards, called racist names by white suburban moms before being assaulted by said white suburban moms, who then called the racist police because of racism. Then when the racist police got there the immediately began rounding up the black people because racism and that one so damn near lost his racist mind due to the proximity of black people that he started doing pratfalls and barrel rolls on the ground and whipping his gun around, because you know everything everywhere is racism. All the time.
The only nonracist person these sweet young well behaved children encountered is that evil black witness who said this wasn't racism and he only gets off on the technicality that he can't be racist because he's black.

The HOA rules are irrelevant.
The lead up to the arrival of the police is irrelevant.
I think it is all relevant as it applies to the context of the events. A number of things could have been done to prevent what happened. I keep hearing about how the teens should have listened to the cops. I saw a lot of kids sitting down as per the officer's orders (why they even needed to sit, I don't know). Why did the Police even need to be involved?
And I think the officer's reaction was appropriate... assuming this was a riot. It was a riot, right?
No bikers were shot so more of a brouhaha.
