"The highest number of officers shot at or shot on record in Chicago. His team members are all shook, as well. It's obviously, the third time this week in Chicago an officer has been shot."

Brown said he was able to speak with the officer who was shot before talking about the dangers his officers face.
So far, this year, according to CPD data, five city officers have been shot, while at least 22 were shot at.
Mayor Lori Lightfoot released a statement shortly after Brown's press conference, calling for gun control legislation.
"I must ask again, when is enough, enough?" Lightfoot said, in part. "How many times must I and my fellow mayors across the country plead with the Senate to take action and end the easy access to illegal guns? How many officers and residents must be victims of gun violence before we act?"
