A consideration to the ending of slavery in the United States was the advent of photography. Film was used to share the horror of the Nazi concentration camps in WW2 because they knew there would be people who deny history. Israel denied access and targeted journalists in Gaza for over a year for a reason.

Public perception sways from indifference to protests when they can’t look away from the destructive results. It’s the whole reason black sites like Guantanamo Bay exist in the first place and were used to hold extradited citizens without due process for years, they want to pretend the Constitution doesn’t exist and they haven’t sworn oaths to it and will do everything they can to hide their crimes.
