This raises an interesting point.
I have seen many videos of the planes going into in twin towers, trucks being used to mow down pedestrians, knife weilding jihadis, ied explosions etc. Even death from drones, apache helicopters and C47 gunships.
None of this deleted from the internet.
Who are the arbiters of what we may and may not see. Who decides what we must be protected from seeing. Who decides what is "hate speech" and what is good talk?
