VIDEO: New numbers on how many city employees have moved out of Milwaukee since the law changed more than four years ago. A Milwaukee Alderman calls it troubling for the city, especially with the biggest numbers being in public safety. About 30% of police officers and 35% of firefighters live outside the city. Some of those are in higher ranking spots in those departments. The police union's take on the numbers? Nothing about the bigger picture has changed. Police officers and firefighters, an integral part of Milwaukee during their shifts and after, but since the rule requiring them to live in the city changed in 2013 there's been a slow trickle out of Milwaukee. A total of 806 officers and firefighters are now living in other communities.
