A 17-year-old, Kyle Rittenhouse, was charged with the shootings, two of which were fatal.
In an interview On Tuesday night before the shooting, Mr. Rittenhouse told a video editor at the Daily Caller, a conservative news and opinion site, that he and other gunmen were there because protecting companies was “our job.”
On the day of the shooting, researchers from the Atlantic Council found that a Facebook page had been created, calling on people to “prepare” and protect Kenosha. One person posted on the page, which has since been deleted, “shoot to kill”.
Another now deleted Facebook page, claiming to represent a group of local militias, asked people to “take up arms” and defend Kenosha from the “evil thugs” who were “planning the next part of the city to burn.” The message was promoted by Infowars and then repeated on hundreds of other Facebook pages.
A person who posted a post in a discussion thread on Reddit wrote that 75 people were on their way to Kenosha from Green Bay, Wis., Adding, “We have a lot of guns. Many tube bombs. “Another Reddit commentator demanded that” all non-whites and degenerates leave Kenosha. “
Facebook removed Mr. Rittenhouse’s accounts on that network and Instagram, removed praise for him on other accounts, and blocked searches for his name, said Brian Fishman, the company’s director of counter-terrorism and dangerous organizations.
In a Twitter thread, Mr. Fishman said Facebook also removed the militia group account for violating company rules, but found no evidence that Mr. Rittenhouse had seen the group’s posts.
