Earlier, Weis disclosed that murders are down 2.3 percent this year.
Through October, Chicago had 379 murders, nine fewer than last year. This year's total could be Chicago's lowest since 1965.
Weis addressed concerns that police relocated to high-crime areas will be taken from low-crime areas.
"We're looking at balancing the workload, and that doesn't mean out of the slow areas we're gonna take officers, because the number of officers they have right now might be perfect," said Weis. "We're looking where there seems to be an abundance of officers, based upon calls for service and other factors, and right now we have our operational folks looking at this. We hope to roll something out in January."
