US Attorney General Merrick Garland begins an investigation into police in Minneapolis, where an officer was found guilty on Tuesday for the murder of detainee George Floyd.
Research should reveal whether the local police are more often guilty of excessive violence.
Justice will see whether the police use excessive force in, among other things, protests that are permitted. Research is also being conducted into discrimination and illegal treatment of people with a behavioural disorder. If necessary, Minneapolis can be forced into police reform.
Garland previously said he would make tackling police misconduct a priority. The previous administration under President Donald Trump limited the role of the national government in monitoring and investigating police misconduct. The Ministry of Justice has reversed that policy.
The ministry previously announced an investigation looking into whether agents in Minneapolis violated the human rights of 46-year-old Floyd. That investigation is still ongoing.
The black American died in May last year during his arrest in Minneapolis. The later fired white cop Derek Chauvin pushed his knee into Floyd’s neck for more than 9 minutes, held in handcuffs on the floor. His conviction is seen as a historic milestone. President Joe Biden called it a “giant step” towards justice.
