Anonymous, the coalition of unidentified international hackers, has undertaken its own pursuit of justice in the Michael Brown case.  The coalition has issued a warning directed at Ferguson police and the Klu Klux Klan to not harm Ferguson Grand Jury protesters.

The videotaped warning came after an Anonymous cyber attack against the KKK followed a White supremacists’ threat of “lethal force” against demonstrators in Ferguson, the hacker group said in online posts and videos.

“You have awakened a sleeping giant,” read an Anonymous flier that targeted the KKK distributed in the St. Louis area. “We will not allow you to harm our families, communities, property nor disrupt our daily lives. Your right to freedom of speech does not give you the right to terrorize citizens.”

Anonymous continued by bringing down a website and seizing two Twitter accounts associated with the White supremacist group. It also revealed the name of alleged Klan members in a campaign referred to as #operationKKK or #opKKK.

“Anonymous won’t tolerate racism in any form, or the suppression of the right to protest,” the group wrote in a blog post on the website

The group followed up with a video posted on YouTube.

“To the KKK and police, be peaceful or you will face the consequences,” the video stated. “To the protesters, do not be afraid. We are here for you and will protect and serve you. We are the law now.”

Anonymous indicated that the video came partially in response to what they saw as a direct threat from Frank Ancona, leader of the KKK’s Missouri chapter, who made a Nov. 11 appearance on MSNBC to defend his threat of “lethal force” against the nonviolent protesters, whom he called “terrorists.”

“We will hunt you down and tear those masks from your face. You’ll be strung up next to the chimps,” Ancona allegedly wrote in a warning to Anonymous members. “The Klan is to be feared, not threatened. Turn away, or face the consequences.”

Anonymous responded by warning that they would not take the threat on their lives lying down.

“When the grand jury indictment is announced soon, we will take every precaution needed to defend ourselves. The protesters will take to the streets peacefully, as they always have,” Anonymous stated in the video, later adding, “Your violent ideology will not prevail in this fight.”

The online protest group also issued a direct warning to Ferguson police.

“If you use violent acts against the protesters as you have before, you should know that you are being watched very closely,” the video stated. “You cannot get away with anything.”

A grand jury on Nov. 24 decided not to bring criminal charges against police officer Darren Wilson in the fatal shooting Michael Brown, an unarmed 18-year-old, triggering massive protests.

Flood Christian Church, where Brown’s father was baptized over the weekend, was one of the buildings torched the night the decision was announced, but it was situated far away from center of the protests and the structures around the church were unscathed. The church’s pastor believes the KKK may have been responsible for the arson, as a form of punishment for his ongoing support of the Brown family.

“Sunday, we do the baptism, Monday, the church is on fire. It just doesn’t add up,” the Rev. Carlton Lee told NBC News.
