It's still not clear what you want.
You want to protest in the USA about George Floyd (so not current events or a broader helping) and treat all the police as adversarials?
A lot of police are black, are mother's, live in small communities so to many of us your view their structure can't be changed is very strange so you need to state it.
Theres a good theory de-militarization of the police short and long term would de-escalate the protests.
You could collate what's on the streets perhaps and look at local laws and procurements.
But I don't know if you even want that? Do you want the protests to slow down?
I want people who are peacefully protesting to be protected against violence that has often been incited upon them by law enforcement.
If I could make all of the protests peaceful then I would. But I would also amplify their message, if I could.
I know this is all very vague, which is why I solicited ideas for concrete steps.
