I haven't experienced something horrible like this, but I really don't understand the purpose if such law suits.
If we want to be able to see things live on the internet, if we want to be able to learn about events in the world as they happen, how can we expect the platforms on which such things are broadcast to take down everything horrible as it happens?
One of the things that has the best chance of limiting the expansion of state power is the ability we all have to broadcast poor behavior of state actors live. If we limit this ability because it gets used for other bad things, aren't we just choosing to give up our ability to hold gov'ts accountable?
