Yet again, a Black man shot dead by police in Philadelphia

 Police in Philadelphia shot and killed a Black man on Monday, triggering protests that saw at least 30 officers injured.

Police said they shot Walter Wallace Jr., 27, after responding to a call about a man armed with a knife.

The responding officers ordered Wallace “several times” to drop the knife and he continued to “advance towards” them, according to a statement. 

They then fired their weapons “multiple times,” shooting him in the chest and shoulder, and he was pronounced dead at the hospital just after 4 p.m., the statement added.

A video capturing the incident and posted on social media showed him walking near two police officers with their guns drawn. The police officers appear to shout at Wallace to put down a knife.

It is not known what occurred before the recording began.

“I have watched the video of this tragic incident and it presents difficult questions that must be answered,” Philadelphia Mayor Jim Kenney said in a statement.

Wallace’s father, Walter Wallace Sr., told the Philadelphia Inquirer that his son struggled with mental health issues and was on medication.

 “Why didn’t they use a Taser?” the paper quoted Wallace’s father as saying. “His mother was trying to defuse the situation.”

The Philadelphia District Attorney’s Special Investigations Unit and the Philadelphia Police Department’s Officer-Involved Shooting Investigation Unit are looking into Wallace's shooting.
