When angry people are protesting on the streets things do sometimes boil over. Opponents of the protests will seize on this immediately, firstly as an attempt to discredit and devalue the protest but also to distract attention from the cause. Opponents of protests have even infiltrated them and deliberately tried to start riots for those very purposes.
Of course the media machine – be it social media or traditional media – of those opponents will go into overdrive, trying to draw maximum attention to any riots and looting (and even fabricating stories about it).
Right now a lot of people around the world are very angry at the institutional racism of the Police in the USA and the continuing abuse and murder of innocent black people. There is no argument that the police in the USA is institutionally racist. The evidence is overwhelming. The question is who thinks it a problem and who does not.
The people that do think it’s a problem are amplifying that message.
The people who think the police should be racist are amplifying the messages about riots and looting.
