The substance of this story was originally announced by a blog called the Last Crusade, which has also claimed that Clemmons converted to Islam while imprisoned in Arkansas. Gateway Pundit picked up the story as well, noting however, that Last Crusade's claim of Clemmons' conversion is unsubstantiated.
A black militant site called "Black Male Felon" seemingly described the protest:
The rally came after a reported emergency meeting held by the [Black Foot Soldiers] movement to to map out plans for a street penitentiary protest and street party that will be held to disrespect tributes, memorials and funerals whites are expected to have for the terrorists.
Whatever the Black Foot Soldiers may be planning, there actually was no "rally." Spokesmen for both the Lakewood and Tacoma, Washington police departments said they had not heard of anything like that going on. The Pierce County Sheriff's office, which is handling the coffee shop shooting investigation, stated unequivocally that there was no such protest.
The truth is actually worse. The Black Foot Soldiers were not protesting, except perhaps online, but they were referring to Clemmons' attack as a protest:
Seattle Black Foot Soldiers say the four people slain in a daring demonstration at the Steele Street Forza Coffee House in Parkland were racist terrorists who caused black citizens to live in fear. (Emphasis added.)
What these groups say is that any killing of whites, including in this case Clemmons' cold-blooded murder of officers Renninger, Owens, Griswald, and Richards, is "a legitimate protest". Black Male Felon celebrates the killings as "Brother Maurice Clemmons' daring stand against white police terrorism." The theme of National Black Foot Soldiers is captured in the slogan: "When whites pay reparations there will be no more black on white crime."
The vitriolic hatred on these sites is enough to turn a person's stomach. The bit of writing contained on these sites is essentially a collage of run-on sentences spewing foul language interspersed liberally with admonitions to kill whitey. They blatantly advocate murder and defend other recent cases of seemingly senseless black on white killings, like the four Oakland police officers killed by Lovelle Mixon, and many, many others.
