Brian Keith Robinson, 41, was fatally shot in Oakland, California, on May 11, 2012. His killing was one of 127 homicides recorded in Oakland that year during a marked rise in violent crime concentrated in parts of East and West Oakland that had become recurring hot spots.

Robinson’s death came amid strains on the city’s violence-prevention efforts: shifting police staffing levels, cuts to programs such as Ceasefire that targeted gang violence, and community mistrust of law enforcement. Those systemic problems — disrupted funding, contested policy priorities, and limited resources — were cited as making it harder to prevent shootings or quickly solve cases like this one.
