I think that's the crux, they do, constantly! We have "real riots" in Spain all the time, and protests, both peaceful and violent ones. We have experience of the actual process of seeing people getting more and more frustrated, and things slowly bubbling until it reaches a threshold, then bubbles over.

This doesn't seem to be that. There is zero political parties/groups involved, which is very uncommon, we have strong groups that are always up for causing some property damages and similar things, when these "real riots" happen, but none of these were involved.

When you have basically groups of individuals all acting in uniform way, based on the same misinformation, with zero association or relation to our existing political factions, then it's quite easy to see that things didn't happen as they "normally" do, that's why people are asking questions right now about it.
