It was a long and bloody weekend in Chicago, where police say at least 102 people were shot between Friday afternoon and early Wednesday, 15 of them fatally. Police say they're "perplexed" and "frustrated" by the scale of the gun violence, which comes after a relatively peaceful Memorial Day weekend, reports the Chicago Tribune. Almost half the shootings happened in the last 12 hours of the long weekend, between 3:30pm Tuesday and 3:30am Wednesday. According to Tribune data, 72 people were shot over the Fourth of July weekend in 2013, which was the last time it spanned four full days.
The deployment of an extra 1,300 police officers in the city failed to stop the violence, the BBC reports. Police spokesman Anthony Guglielmi says many of the shootings happened when petty disputes escalated into somebody pulling a gun. "People drinking all day and then things escalating ... It's just enormously frustrating," he says. Guglielmi says a review of the weekend will include a look at whether the new "ShotSpotter" system, which tries to quickly deploy officers when shots are heard, might have been affected by fireworks.
