CHICAGO (CBS) — Fireworks will sparkle in the sky over Lake Michigan Saturday night, according to an announcement made as aldermen and Chicago Police Supt. David Brown had a safety meeting ahead of the potentially violent weekend.

Mayor Lori Lightfoot announced the fireworks on Friday, saying it is an excellent way to kick off the summer everyone has been waiting for, but there are concerns among city leaders about crime Saturday and Sunday, which is traditionally the most violent weekend of the year.
