Residents in Ferguson, Missouri, on Wednesday night were once again demonstrating in protest of the controversial shooting death of 18-year-old Michael Brown.

Since Sunday, there have been riots, multiple arrests, looting and some violence in the disgruntled St. Louis suburb. Police have responded with heavy-handed tactics, using military-style vehicles and tear gas in an attempt to quell the unrest.

Ferguson Police Chief Thomas Jackson, who has been the public face of the city torn by Saturday’s death of Brown, told reporters earlier in the day that the St. Louis County investigation of the shooting could take weeks to complete. In the meantime, he said, his department welcomes Justice Department training on racial relations in the suburb, where two-thirds of the 21,000 residents are black while all but three of the police force’s 53 officers are white.

“Unfortunately, an undertow (of racial unrest) has bubbled to the surface,” said Jackson. “Race relations is the top priority right now.”

Two reporters were also reportedly arrested and then released without charges after they apparently failed to clear an area fast enough.
