About that increase in voter registration in Ferguson, MO since the killing of Michael Brown...

As it turns out, not so much. MSNBC's Zachary Roth reports:

Local election officials said last week that 3,287 people had registered to vote in Ferguson since the Aug. 9 police shooting of Michael Brown—a massive spike in a city with a population of 21,000.

 

But Tuesday, the board backtracked, saying that in fact only 128 people had registered.

Heard Days told msnbc that the 3,287 figure in fact showed how many already-registered voters had had a change made to their registration information—for instance, because they moved within the county. Board officials wrongly thought the number referred to newly registered voters.
