Rebecca Hersher writes: "The most emphatic statements on Roof's behalf came from defense attorney David Bruck. For weeks, the prosecution had presented evidence that Roof is a white supremacist whose violent racism drove him to kill black people. Bruck asked the jury to consider how the 22-year-old came to believe the things he did.
As NPR reported: " 'There is hatred all right, and certainly racism, but it goes a lot further than that,' [Bruck] said." 'Every bit of motivation came from things he saw on the internet. That's it. ... 'He is simply regurgitating, in whole paragraphs, slogans and facts — bits and pieces of facts that he downloaded from the internet directly into his brain.' "
Bruck was referring to Roof's assertion in his confession and in a manifesto that a Google search shaped his beliefs.
I use YouTube purely for recreational purposes--and the occasional "how do I replace [insert random broken household item]"-- but I just spent some time looking at various controversial topics. Sure enough, click on one anti-vaccination video, and all the recommended videos become anti-vaxx, even though when I did a simple [vaccination] search, the first page of videos were predominately pro-vaccination.
When I teach about doing Internet research I always talk about staying focused, since it's so easy to get distracted by irrelevant sites. My example is always YouTube. I ask students to raise their hand if they've watched a YouTube video for fun. Then I ask them to raise their hand if they stopped at that one video. No one does. Now, instead of just emphasizing why that rabbit hole can cost them research time, I'll be asking students to be more aware of where that rabbit hole might take them.
