Dallas Humber, a 34-year-old woman from Elk Grove, California, has been arrested for co-leading a white supremacist terrorist group called the 'Terrorgram Collective', alongside Matthew Allison from Idaho. The group is accused of using the Telegram app to incite hate crimes and plot attacks against government officials, promoting a violent ideology centered on white supremacy. Federal prosecutors allege that they provided their followers with instructional materials on creating weapons and committed to targeting individuals based on race, religion, and sexual orientation. Among their targets were a sitting U.S. senator and a federal judge, with the group allegedly celebrating past violent incidents and seeking to instigate a race war. This indictment highlights the Justice Department's commitment to countering the rise of violent extremism facilitated by modern technology. Both Humber and Allison face multiple charges, including soliciting hate crimes and conspiring to provide material support to terrorists.
