I think it's come to a point that there needs to be concrete demands, legislature suggestions, or something... Don't get me wrong, I completely understand what do protestors actually want, but this way it will die down and again nothing will change. While on the other hand, I do understand that tere is or may be a fear of stepping up, because if somekind of organisation does, they could easily be branded as "terrorist". That shit that Trump spewed about making "antifa" a terrorist organisation wasn't something that I expect to happen (it's also very unclear if that would be unconstitutional) but it was a very clear warning shot. If a movement tries to step up more, they will spin it the way they want, and a good portion of the country will eat it up.
I can also imagine that individual people have a fear of stepping up, since some of the leaders from the Ferguson protests have been murdered on their doorstep, or found in torched cars. Some of them are alleged suicides.
I share the sentiment of EJ! also. I would also like that the looting doesn't happen, and I don't condone it. But sadly it's always a part of the riots, not just in the US. It happened also in Hong Kong, but I didn't see that it was so heavily taken in the account then. In Honk Kong after months and months of protests, 2 people died. In less than a week of Floyd protests, at least 5 are dead. And the examples of ongoing police brutality and tyrannical behaviour were the exact very reason for the protests. These kind of riots also get infiltrated by the police, by groups of people who want to make it look like the looting is the main reason and the main part of the protests. It is a complex thing, always was. Notice how the HK protests were never called "riots", but the narrative of the Floyd protests were quickly taken a hold as: "oh these are not protests, this is just pillaging and looting".
Also, the international community is very *censored*ing silent about the whole thing. They were given shit how they don't have the balls to stand up to China in the wake of HK protests, but now, only some mild reactions by some organisations while the police reaction to the protests are much more brutal.
In the end, all of this was to be expected at some point. It was a powder keg waiting to happen, frustrations, division on all kinds of fronts and opression have been happening for decades. And the worst part is, these protests won't bring to some structural reform. That's not the way this country was set up. There is always some hope that after Trump the country will begin to heal. But I don't see it yet. The cultual and civil degradation has been happening for decades and decades.
