Agree 100%. And, on top of the reason you gave for it to be important for some people to see, it’s also important to keep as a historical record. But I personally do not need to see or hear people dying or people not reacting despite knowing other people are dying to be upset about the situation or to want to hold those responsible to account.
I’ve never seen George Floyd’s murder. That did not stop me from protesting the police murdering him because… you know… they murdered him.
