Baltimore Riots 
About 20 businesses and more than 140 cars burned as the mayhem spilled into Tuesday's early hours. From 1 a.m. to 5 a.m., the city's Office of Emergency Management reported 10 major blazes.

Police Commissioner Anthony Batts said the young age of those who took to the streets with rocks and bricks -- high school students, many of them -- caused officers to take a measured initial response to Monday's violence.


But as a relative calm prevailed before the 10 p.m. curfew took effect, Baltimore's school system announced it would reopen for classes Wednesday.

"Acts of violence and destruction of property cannot and will not be tolerated,'' Hogan said. "This is far from over.''

The Baltimore Orioles canceled Tuesday's scheduled home game and in an unusual move said Wednesday's game will be played in an empty Camden Yards stadium, without spectators.

Baltimore residents used social media to show cleanup efforts Tuesday morning and post video diaries of their reflections on the violence that erupted after Freddie Gray's funeral Monday. 

The nation has seen a barrage of images of the rioting that erupted in the city Monday,  there were also peaceful protests. There were residents thanking police. And on Tuesday, with schools closed and streets quiet, volunteers worked to clean up their city.
