What we know today about Ferguson

There's still no word on whether a grand jury will indict officer Darren Wilson for the shooting death of Michael Brown.

Ahead of that announcement, here's what we do know:

• A grand jury decision expected as early as this weekend on whether to charge Wilson in the shooting death of Michael Brown appears to be delayed until Monday at the earliest, according to a federal law enforcement official.

The St. Louis County grand jury is expected to reconvene Monday, according to the official who spoke to USA TODAY on condition of anonymity because he was not authorized to comment publicly on the matter. The timing of a decision is still unclear, the official added.

• Police and protesters are planning ahead. Police leaders have met five times with some protest group leaders, resulting in them agreeing to 11 rules of engagement, such as avoiding the use of excessive force and communicating to de-escalate tense situations.

• President Obama and Attorney General Eric Holder have called for people to temper their reactions. The president spoke during an ABC News interview, saying people who were upset shouldn't use the grand jury's decision as "an excuse for violence."

For his part, Holder urged law enforcement officials to minimize the potential for confrontations during demonstrations.

• Joining in the call for calm is Michael Brown's father. In a video statement released Thursday, he said he, his family and the entire region "are hurting. ... But hurting others and destroying property is not the answer."

• If violence or unrest does erupt, Missouri Gov. Jay Nixon will call in the National Guard. He declared a state of emergency earlier this week.

• Some schools in the area are preparing for what comes next. The Jennings school district decided to close its schools on Monday and Tuesday, lengthening the Thanksgiving break for its students and avoiding having them in school during potential demonstrations.

• Regardless of what happens, Wilson reportedly is resigning from Ferguson's police force.
