An Atlanta coalition called "Shut It Down Atlanta" plans gatherings at Underground Atlanta at 5 p.m. Tuesday, the day after the Ferguson grand jury decision is announced.

From a message posted on its Facebook page on Monday:

"As we speak, a grand jury is convening in Ferguson to decide whether or not Darren Wilson will be tried for the murder of our brother, Michael Brown. There has been no transparency about when the verdict will drop, but Atlanta needs to be ready to hit the streets whenever it does! Our government doesn't value us enough to deem us worthy of honesty, so this is a time to stay WOKE."

"A coalition of organizations have planned a vigil being held immediately after the verdict...Plan to participate. Plan to speak out, and be loud. Plan to be heard. We cast our vote, family. In the ballot box, and on the block. Police brutality must end. It is Unanimous."

The hashtag #shutitdownATL has been busy on Twitter amid updates out of Ferguson.

"It is time for ATL to rise up! One of the best ways we can express solidarity with other cities is to stand up for justice on our own," the group's message continued. "We don’t know what the outcome of the grand jury will be. We do know that the Ferguson PD's unjust killing of Michael Brown is one among many, that killer cops are almost never held accountable, and that our communities experience violence on a daily resulting from forms of abusive policing."
