(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.
Meanwhile, Attorney General Eric Holder traveled to Ferguson to check in on the ongoing federal civil rights investigation that already includes more than 100 witness interviews and an independent autopsy.
"My hope is that it will give people some confidence that the appropriate things are being done by their government," 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.
