As far as rational, controlled, and motivated anger goes, what day these events happen on should not stand in the way. This needs to be harnessed to enact massive structural change of course, not online flame wars or unproductive methods of protest. Still, that very anger you see is also able to be used to motivate many people to add in ways they may not have before. White people are starting to understand that they can be used as literal shields [1] against police brutality, and that should not be lost in this. There is much to be gained in a positive way from this anger.
I do appreciate your general sentiment here, I just wanted to underscore that the anger here, particularly that felt by POC, has deep roots beyond these incidents and can be used positively. I think that caveat is where we agree - how to harness that anger.
