St. Louis, November 20 (RHC)-- Protests continue in Ferguson, Missouri, ahead of the grand jury’s decision on whether to indict Officer Darren Wilson for the killing of Michael Brown. On Wednesday, demonstrators braved sub-zero temperatures to rally outside the Ferguson Police Department.

Speaking in New York, civil rights leader Al Sharpton criticized Missouri Gov. Jay Nixon for declaring a state of emergency in the absence of any unrest. Sharpton said: "There’s a lot of tension out there, and I do not think it's helpful when the governor (of Missouri) lectures and does not have a balance."

In related news, the U.S. white supremacist group the Ku Klux Klan has threatened protesters in the city of Ferguson with “lethal force” should their demonstrations become violent.

Members of a Missouri-based branch of Klu Klux Klan handed out some threatening fliers around St. Louis County in the U.S. state of Missouri. Traditionalist American Knights of the KKK head Frank Ancona said last week that he has received hundreds of phone calls from people concerned about “random attacks on whites, D.C. sniper-style shootings.” He added that the fliers would educate people on what rights they legally have to use lethal force in self defense.

On August 9th, Wilson gunned down 18-year-old Brown, claiming it was an act of self defense. The jury will either indict Wilson or will decide that he should not be tried on criminal charges.

Ferguson has been the scene of public demonstrations since the fatal shooting. Last month, Ferguson Mayor James Knowles warned the authorities to be prepared for the “worst” after the grand jury delivers its decision. The grand jury’s decision on whether to charge Wilson is expected any day.
