Shooting an unarmed protestor who is merely trespassing is absolutely an execution. Just as Rittenhouse's shootings were.
And Rittenhouse was clearly looking for trouble, i don't think a black perosn could Go fully armed to a KKK rally and claim self defense if started shooting people after beeing harassed there.
There have been a lot of violent protests in the last 12 months, this being just the latest example. It’s nothing if not a great litmus test for anyone speaking or writing about protestors or policing protests.
