VIDEO: Warning signs being installed by the Milwaukee Fire Department on vacant homes in the city are causing a bit of a dispute. They are being put up to help reduce risk in a fire, but that is not the way some city leaders see them. The placards are being nailed on some of Milwaukee's most run-down, abandoned homes. The signs are posted as part of the fire department's vacant structure placarding program, which is designed to prevent unnecessary risks, but recent installations are sparking concern. "I have big problems with this. This is essentially putting a scarlet letter on a lot of the properties in our neighborhoods," said Milwaukee Alderman Bob Bauman.
