Not only do I agree with that, I would like to make a really important point, which is that the design of the Internet itself is part of the problem. I'm of the generation—as Jim is as well—that was around when the Internet was originally conceived and designed. The notion in those days was that people could be trusted with anonymity, and that was a mistake, because bad actors use anonymity to do bad things. The Internet has essentially enabled disaffected people to find each other in a way in which they could never find each other in the real world and to organize in ways they could not in the real world.
When we're looking at Christchurch, we have to recognize the first step, which is that this was a symphonic work. This man went in and organized at least 1,000 co-conspirators prior to the act, using the anonymous functions of the Internet to gather them and prepare for this act. It was then, and only then, after all that groundwork had been laid, that the amplification processes of the system went to work. Keep in mind that those same people kept reposting the film. It is still up there today.
