Before the Charlottesville “Unite the Right” rally, white supremacist attendees were planning violence, as leaked online chat screencaps reveal.

On a private chat, they discussed violent tactics and weaponry, and even mentioned driving vehicles through crowds of counter-protestors, which of course happened.

After Heather Heyer was killed by a vehicle at the rally, members of the chat celebrated.

The private chat was created using Discord, a chat mostly used by gamers.

Hundreds of screencaps revealing the inner discussion were released recently by a left-leaning activist group called Unicorn Riot, which allegedly got them from an anonymous source. The release even included audio recording of planning meetings.

According to Fortune:

“While much of the discussion centered on flags, chants, and other forms of speech, the leaked exchanges also included advice on weapon construction. “You want something designed for longitudinal stress,” wrote one poster. “[Three] whacks and that thing is breaking.” Other topics included body armor and shield design.

Users also shared memes alluding to using vehicles against opponents.”
