The protests/riots aren't that bad IMO, this kind of stuff happens. What is bad is the root cause - an elected official fighting tooth and nail to retain power after being voted out, and finding real support among a large fraction of the population.

A sieged Senate just doesn't fall into 'stuff happens'. The last it happened was by the hands and torches of British troops during wartime.

See eg https://en.wikipedia.org/wiki/Oscar_L%C3%B3pez_Rivera (off the top of my head, there are probably others).

If you extend to the states, it's not that exceptional:

What the Panthers did in California is not comparable at all. I encourage you to listen to the account of the day in their own words.

They came armed (nominal, as they went armed everywhere) to a peaceful prearranged meeting at the statehouse. The media turned it into a crazy narrative because black men carrying long arms were photographed inside the statehouse.

There are other countries on the planet. Rioters breaking into parliaments is not exactly common, but it's not particularly shocking either
