A public petition calling for US police to wear cameras will receive White House consideration after the killing of an unarmed teen in Ferguson, Missouri prompted days of tense protests. Under a program established by President Barack Obama’s administration, the White House is compelled to review and officially respond to a petition if it receives more than 100,000 signatures.

As of early Monday, the petition to create the Mike Brown Law, named after the 18-year-old shot by police and that would require all state, county, and local police to wear a body-worn video camera had more than 112,000 signatures.

The petition, according to its text, is "an effort to not only detour (sic) police misconduct (i.e. brutality, profiling, abuse of power), but to ensure that all police are following procedure." Ferguson has been plagued by protests and race riots following the August 9 shooting of Brown, an unarmed African-American teenager.

The majority black population city’s police force is predominantly white and the shooting and subsequent reaction has focused national attention on the continuing problems with race relations in America, particularly between security forces and young blacks.

Governor Jay Nixon declared a state of emergency and a midnight curfew after looting and violence overnight Friday, and Missouri’s National Guard has been deployed to restore order.
