(NBC News) Heavy rains slowed the protests overnight in Ferguson, Missouri.
Crowds remained peaceful and only a few arrests were reported.
On Wednesday the cry for justice came outside a St. Louis courthouse, where a grand jury met for the first time to hear evidence in the shooting death of unarmed teenager Michael Brown.
Attorney General Eric Holder traveled to Ferguson on Wednesday to check in on the ongoing federal civil rights investigation that already includes more than 100 witness interviews and an independent autopsy.
"It doesn't mean that this thing should drag on. We will try to do this as expeditiously as we can. on the other hand at the end of the day it's most important that we get it right," Holder said.
Holder met privately with the Brown family after talking with members of the community, elected officials and Captain Ron Johnson, the Missouri State Highway Patrol officer charged with trying to keep the peace along the front lines of the protests.
