Arguably? They placed themselves in more danger by swerving back towards the crowd. All so they could get revenge for some minor property damage.

The accounts prior to the start of the video are conflicting so I won’t comment on that but it’s clearly not self defense to strike someone from behind with a vehicle when you have a clear route of egress. That’s attempted murder.

And protestors are protestors. That doesn’t change based on your feelings being hurt or whatever it is that’s causing you to say that. Most major protests have used roads across all of history. But I guess MLK’s march on Washington wasn’t a protest either?
