Violence is sometimes the only way forward, though. It should be the way of last resort, but a way nevertheless. That's why we have democracy: so we can remove the people in power by ballot instead of by guillotine. When the former avenue is blocked, violence is all that remains...

Doesn't this go right back to thinking things through before attacking people people?

Right or wrong, when people are abused repeatedly, and or they cease to believe in governance, they will act out and it won't all be nice.

The root cause here is an authoritarian regime failing to justify their authority. People acting out is a symptom.
