Black Lives: Thousands of police and troops are deployed in Baltimore today following a night of rioting and looting that broke out after the funeral of 25-year-old Freddie Gray. The governor of Maryland declared a state of emergency and called out the National Guard.

At least 15 police officers were injured and 200 people were arrested. Police say they received a “credible threat” that three street gangs have teamed up to “take out” police officers.

The violence started several hours after more than 2,200 people attended the funeral of the young man who died as a result of injuries suffered in police custody. Rioters threw rocks, burned cars, and looted stores. A major shopping center was looted.

Mayor Stephanie Rawlings-Blake announced a weeklong 10 p.m. to 5 a.m. curfew. She said, “We will have order. We will have peace.”

A police spokesman said the cops would be tough. “You’re going to see tear gas. You’re going to see pepper balls. We’re going to use appropriate methods to make sure we can preserve the safety of that community.”

   More than two weeks after Gray was arrested and ended up in the hospital fatally injured, investigators still have not explained what happened.
