I just want to point out that most of the other time you hear about “attacks” on art the piece is perfectly fine. They’ll attack pieces shielded by glass. It makes a statement and does no damage (maybe a little mess to clean up). Like the recent Mona Lisa “attack” you can’t miss that it’s covered by glass as you’re spending 30m getting closer. It wasn’t a mistake that no damage was done.
I do agree in this case it’s fairly justified. This man doesn’t deserve to be remembered fondly.
