Ferguson Grand Jury Still at Work

Tensions are high as grand jury considers whether to indict Darren Wilson.

— -- A grand jury in St. Louis County, Missouri, is expected to reconvene today, trying to decide whether to indict a white police officer in the August shooting death of an unarmed black teen.

The Saint Louis County Police Department switched its officers to 12-hour shifts in recent days. Metal and concrete barricades have been erected in areas around the St Louis County government buildings in Clayton, Missouri, where the grand jury has been meeting. The justice center there also houses the prosecutor's office, the St. Louis County Police Department headquarters and the circuit courts.

A handful of arrests were made during the weekend. Some stores in the St. Louis suburb remain closed, with business owners boarding up windows in fear.

“We look abandoned here, pretty much imprisoned,” business owner Triondus Sleet said. “It’s sad.”

“It would be my hope though that if, one day, he decides to stay in law enforcement, that he's able to do that,” said Detective Gabe Crocker, president of the St. Louis County Police Association. "Especially if he’s cleared, that means he didn’t do anything wrong, according to the grand jury."

“Using any event as an excuse for violence is contrary to rule of law and contrary to who we are,” Obama said.
