I see that last shooting thread is going great in response to that witness picture.
I guess people are (willingly?) missing the point: it appears that anything that was said by the previous witnesses was bollocks. The cops ARE wearing uniforms. There IS a gun. But now it's down to discussing whether that gun could be lethal enough

And I think this perfectly illustrates that some arguments made in the rape/abuse thread, namely "well innocent until proven guilty only applies to courts, people can discuss that stuff online" is madness. If not for social media, all the shit that's going down now would never have happened. So no, it's not just "discussing it online".
Unfortunately, I don't think there's any way to prevent these things now.
