The Chicago Police Department says it is conducting "a very comprehensive review" after the city experienced one of its most violent Fourth of July weekends in recent years, with at least 102 people shot between late Friday afternoon and early Wednesday.
"We're doing a debriefing," said chief police spokesman Anthony Guglielmi. "The mood here is frustration."
The review will include an analysis of how "amateur fireworks" might have affected the ShotSpotter system, which captures audio of gunfire and attempts to pinpoint its location for quicker deployment of officers. The system is deployed in the Englewood and Harrison districts, traditionally among the city's most violent.
"It's perplexing," Guglielmi said. "We deployed some very successful tactics over the Memorial Day weekend." Yet those same tactics did not seem to work as well over the Fourth holiday.
