In addition to a prompt, thorough, independent and impartial investigation into allegations that police shot dead an unarmed teenager in Missouri, an investigation into the use of heavy-handed tactics to disperse a wave of protests in the wake of the shooting must be launched without delay, Amnesty International said.
"What is now urgently needed are thorough investigations, not further inflammation, of the incredibly tense situation in the aftermath of Michael Brown being shot dead," said Steve Hawkins, Executive Director at Amnesty International USA.
"Any police officer suspected of having committed unlawful acts must be held to account through effective investigation and, where warranted, prosecution."
"Using excessive force to quell protests is unacceptable. Police in Ferguson must conform to the US Constitution and international standards on the use of force and firearms. Residents must be allowed to peacefully exercise their right to freedom of expression and journalists must not be prevented from carrying out their work."
The call comes after police last night again used tear gas and rubber bullets to disperse a demonstration in Ferguson, the St. Louis suburb where an unarmed African-American teenager, Michael Brown, was shot dead by a police officer on August 9. According to media reports, police arrested at least 10 people during last night's protest, as well as two journalists who were covering the story yesterday afternoon.
On August 13, Amnesty International USA wrote to the Ferguson Police Department in Missouri to express its deep concern over the shooting of Michael Brown and the use of tear gas and rubber bullets at a demonstration against his death on the evening of August 11.
International standards on the use of force and firearms require that police should apply non-violent means before resorting to the use of force. The intentional lethal use of firearms is only permissible if strictly unavoidable in order to protect life.
