The protests street vendors returned Monday night to the American city of Philadelphia after the death of another black man by police shooting.

The demonstrations started after a man identified as Walter Wallace, 27, was shot dead by two officers. According to the body, the police officers shot him “several times” in the chest and shoulder after demanding that Wallace put down his knife. The man was taken to the hospital but died of gunshot wounds.

Hundreds of people came out to express their discomfort in the streets. Several cars were set on fire and, according to the police, some 30 officers were injured and a dozen arrests were made.

The protests in Philadelphia add to those recorded for months throughout United States after death in May George Floyd, a 46-year-old African American who was put in the neck by a Minneapolis police officer for nearly nine minutes, resulting in death from asphyxia.

Video under investigation

The mayor of the city, Jim Kenny, and the police commissioner, Danielle Outlaw, explained that the incident is under investigation.

As can be seen in the video of the shooting broadcast on social networks, recorded by a passerby, the two officers point their weapons at Wallace as he walks down the street. When he notices, Wallace walks up to them, who back off with guns still pointed at him, as they yell at him to put the knife down. After this, both shoot several times and Wallace collapses in the middle of the street.

The American Civil Liberties Union (ACLU) condemned police action and considered that state violence cannot be the answer to society’s problems. “Time to invest in community programs, including the kind of mental health services that allow the intervention that could have prevented the murder of Wallace, “he said.
