Dr. Brantly says, it is a miraculous day.The rain helped keep things calm in Ferguson, Missouri Wednesday night. The town is been on edge since an unarmed African-American man was shot and killed by a white police officer. Protests, some of them violent, have been almost constant since then. Most are in support of 18-year old Michael Brown. Eyewitnesses say he was trying to surrender when Officer Darren Wilson shot him on August 9. Some demonstrators have turned out to support Officer Wilson. Police say, Brown struggled with him and reached for the policeman is gun before the shooting.A grand jury has been assembled. This is a group of people who will look at the evidence and decide whether Officer Wilson should be charged with the crime. That process could take several weeks.
