The FBI is searching for the suspect in a terrorist bombing outside an NAACP office

Authorities are looking for a man who may have information about a homemade explosive set off near the Colorado Springs chapter of the NAACP on Tuesday. There were no injuries and only minor damage, police said.   + The blast happened Tuesday outside a barber shop that's next door to the group's office. An improvised explosive device was detonated against the building, but it was too soon to know whether the nation's oldest civil rights organization was the target, FBI spokeswoman Amy Sanders said. + The bombing, coming in the midst of nationwide protests against police mistreatment of black citizens, recalls the sad history of violence against the NAACP. + Mic's Derrick Clifton: "Make no mistake: Attacks like these are unacceptable and reinforce a history of anti-black racism that's meant to deter any progress made toward racial justice.
