It isn't over: DOJ still has two investigations into Michael Brown shooting open,

16. True, but the DOJ has already sent the Ferguson police dept two letters

of reprimand, one telling them to knock off the "I am Darren Wilson" armbands and another telling them to make their name badges visible. And the investigations are still under way, so I wouldn't be surprised if the DOJ brings charges or puts the dept under DOJ control or takes some other drastic measure. It's a small dept., not like New York or L.A., but come to think of it the L.A.P.D. was eventually sued by the DOJ after Rodney King and put under DOJ supervision for several years. So it's certainly possible, though it won't happen right away.

p.s apparently it took eight years to secure the LAPD consent decree:

The Los Angeles Police Department is today completing one of the most ambitious
experiments in police reform ever attempted in an American city. After a decade of
policing crises that began with the beating of Rodney King in 1991 and culminated in the
Rampart police corruption scandal in 1999, the U.S. Department of Justice announced in
May 2000 that it had accumulated enough evidence to sue the City of Los Angeles over a
pattern-and-practice of police misconduct. Later that year, the city government entered a
“consent decree” promising to adopt scores of reform measures under the supervision of
the Federal Court.
