Investigations into his social media history took place. Motive Clyde appears to have self-radicalized online, posting memes related to the incel subculture that appeals to men who feel lonely and alienated, and, ultimately, getting "sucked into a hateful vortex that tells them that their lives are only valuable if they go out bringing death" to others. Clyde had uploaded extremist far-right memes including ideas about the Confederate States and Nazism. Some of his posts were transphobic and others were anti-feminist. In April 2019 he posted a meme suggesting that combining eco-friendly and libertarian ideas with far-right authoritarianism, symbolized by what the Daily Beast describes as "a green flag with a Nazi swastika in the middle", could be the "solution to all of our nation’s political problems." Clyde's family believed that it was a case of suicide by cop. Aftermath A Maryland Air Force base was inspired by the Dallas shooting to initiate a program teaching personnel to recognize the warning signs that "introverted, sexless individuals" may be drawn to the "incel" online subculture. On March 18, 2020, a man pleaded guilty to threatening to assassinate the governor of New Mexico, Michelle Lujan Grisham. He cited Clyde as an inspiration for his desired attack. On May 4, 2020, Tom Fox was nominated for a Pulitzer Prize for Breaking News Photography for his photographs of several people fleeing, Clyde himself, and Clyde being attended to, respectively. However, the prize went to Reuters for their photography of the 2019 Hong Kong protests.
